Forest Bathing Equals Nature Immersion

Although I have heard of “forest bathing,” I have not actually experienced it until this past month. Having graduated with a degree in clinical mental health therapy, my daughter was interested in nature as a therapy tool and I recommended forest bathing. I wanted to experience it with a certified guide so I booked two tickets from the Friends of the National Arboretum (FONA) for a Saturday morning at the U.S. National Arboretum.  According to the FONA site, forest bathing, or shinrin yoku, is the simple practice of taking in the woods through the senses. The benefits are immense: boosted immunity, lowered blood pressure, and improved attention and mood.

Unfortunately, in the interim, my daughter was offered a position in another state and was not able to attend but I promised her I would write about it here so she could know what it was like.

This particular event was from 9:00 am to 11:00 am and even though the instructions said that it would take place despite light rain or snow, I thought for sure it would be cancelled. The forecast called for rain, and I kept looking at my phone for the cancellation email. Seeing none, I drove to the Asian collection within the Arboretum and met my guide, Paul Jarris. There was a light drizzle but I was prepared with my umbrella, poncho, backpack, weatherproof shoes, and water bottle.

We gathered in a circle and introduced ourselves. Although the event was sold out, 8 showed up. Probably the rest did not want to come out in the rain. All of us were new to forest bathing. Everyone was a DC resident except for me and Paul.

Paul is a certified forest therapy guide. I had hoped that my daughter could ask the guide about forest bathing training and the science behind it. For me, I wanted to learn forest bathing techniques — not just walk in nature.

Forest bathing has ancient roots in Japan. In the 1980’s, many Japanese were working too hard, were too stressed. The director for the Japanese Ministry of Agriculture, Forestry and Fisheries knew of the health benefits and employed it as a government sponsored initiative to help stressed employees and improve preventative health care.

Paul briefly talked about this history, the process, the health benefits, and what forest bathing was not. It was not a hike, it was not plant identification, and it was not meditation. Meditation turns your attention inward while forest bathing turns your attention outward.

We walked a few minutes on an asphalt road to the crepe myrtle grove which is like being in a forest but not a true forest. As we walked, he asked us to think back to our happy times in childhood.

“I like to start with that because almost all of us have some childhood memory when we don’t have the inhibitions of an adult,” explained Paul. “We’re just in a more natural state. It is one of the ways to remind people of that, to get them a little bit out of their head and back into their memories and feelings, that notion of getting out of the adult mind and into the child mind, the creative mind, the less inhibited mind.”

I tried to think about this as we walked but the group was quickly coalescing and we ended up talking with each other. By the time we got to the crepe myrtles, the rain stopped. For August, it was a beautiful cool morning — the weather could not have been more perfect.

In a grassy clearing surrounded by tall, pink and red blooming trees, Paul instructed us to close our eyes while standing and to focus on our senses. He asked us to listen to the sounds far away and nearby, feel the feet on the ground, feel the breeze and our clothes against our skin, taste the air with an open mouth, and smell the air and the freshly washed grass and trees. We did this for about 10 minutes. We then opened our eyes and shared what we experienced. I noticed or had not noticed before that there are sounds in the distance (trucks) as well as nearby (birds) but also that there was “taste” (a bit of moist earth), and “touch” — the wind slightly caressing the arms. I became aware of layers or dimensions.

This was our first “invitation” called “Pleasures of Presence” or “POP.” Invitations are suggestions by the guide to focus on something and can differ depending on your guide.

“This really gets you to open your senses and it really does start to get you into the forest and all the ways that nature enters and causes the healing,” said Paul. “You can see how people are noticing things like, wow, I’ve never thought of sound as far away or close or the different levels or layers of sound or how vivid things are when you open your eyes.”

After each invitation (four in all), we shared our experiences. Our small size was ideal because we each had enough time to talk. Although the Arboretum caps forest bathing around 16 people I think we were lucky it rained which culled it down to 8. Depending on the space in other locations, groups can be small or large but small makes it more personal. I was struck by how quickly we opened up and talked with each other. However, I do not know if that was because of the nature setting, the small size, or the fact that we were all women except for Paul and another gentleman.

The second invitation was to walk around to see what was in motion. Paul said to not worry about time, he will make a “coyote call” when it is time for us to come back. I walked around the grove, looking at the crepe myrtles. I noticed the bees high up, buzzing around the flowers. At eye level, a few spent blossoms fell loose and dropped to the ground. At waist level were long branches of leaves and flowers swaying in the breeze. We observed for about 10 minutes and then heard the “coyote call” which was really Paul making a loud sound. We came back to the clearing and standing in a circle, we shared what we saw, felt, and thought.

Paul explained that the “what’s in motion” invitation is a way to slow down for you to begin to notice everything around you that you typically take for granted or don’t think about. “Everything’s moving, even on calm days, including the insects and the leaves.”

The third “invitation” was to find something to focus on for about 10 minutes. I had noticed that there was a sunny grassy clearing outside the grove with a small area of tall weeds. I wondered why the weeds were growing there and not anywhere else. As I got closer, I discovered a tree stump so wide it could have been a children’s bed. I sat on the stump looking at the weeds, the ants, and the singular pokeberry growing out of a crevice. It had been a very old tree; I tried counting the rings but there were too many.

At one point, I put my hand into my pocket to get my iPhone and realized that it was simply a reflex to pull it out and look at messages. Fortunately, I caught myself and stopped. It went without saying that the phones should be off during forest bathing.

When we came back, I described the tree stump and how it made me think of time past, little time left, death, and the many generations before us. Paul said the tree had been there since the Civil War because staff found Civil War artifacts near it after they had to cut it down due to disease. He explained that there is so much to see and think about when you look at a plant or a tree, everything it supports, the whole ecosystem, but just looking at it and how it developed — there’s such a story there. He said it is wonderful when people take some meaning from that into their own life. Our group in particular went very deep, tying back lessons to life. “It’s so rewarding to see a group get like that and not just be superficial and say “Oh, I noticed the green leaf, a red leaf, and a purple leaf.” He told us that in one forest bathing group there was a woman whose middle-aged son had recently died. She said her son came to her through a big oak tree which symbolized strength, and her son had that strength. She felt her son was telling her, “I’m okay, Mom, and you’re going to be okay.”

For the fourth and final invitation, which Paul called the sit spot, he gave us mats for us to sit on in front of something. I sat under the shade of a crepe myrtle and looked at a very tall but dead tree with no branches or leaves. Although I could not see anything from my vantage point, I knew it must be home to wildlife and full of insects. As I sat looking at the tree I thought about life and death again but also invisible life. Life we cannot see whether it is insects in the wood or spirits (the Arboretum was home to indigenous people many years ago).

Hearing the coyote call, we came back to a large blanket on the ground. As we sat on the blanket and shared our experiences, he distributed plastic cups and offered us our choice of cinnamon or mint tea from thermoses.

In traditional forest bathing, the event ends with tea and a snack. If this were in Japan, the guides may gather twigs and leaves from the forest to brew a tea for a formal tea ceremony. However, because of the recent pandemic, Paul now uses disposable cups and because we were in an arboretum where picking was prohibited, he brought the tea.

We spent time talking about life in general and it was not until it started to sprinkle again that some of us got up to leave. Interestingly, it was as if we had made fast friends in those brief 2 hours. And the time did fly. Paul explained that ending with tea is a way for us to transition back to real time. Because we spent 2 hours looking at trees and plants, we were in “subliminal time,” where you do not have a sense of time but are very focused on the here and now.

To me the words “forest bathing” are not truly descriptive of the experience or have little meaning to people who have not done it. I know the words cause confusion. Forest bathing is really “immersion in nature” or “nature immersion,” composed of three major parts: 1) disengagement from your daily routine (go to a place in nature where you can focus on nature and turn off your phone and other distractions); 2) connect with nature through listening with all of your senses and looking at some particular part of nature; and then 3) transition back to daily life with tea and/or snack or something reflective like reading a poem.

As we experienced forest bathing at the Arboretum, Paul cited numerous studies that showed the positive impact. There are too many to recount here but since the 1980s, there have been studies in several countries that examine the physiological and psychological effects of forest bathing. Here in the United States, within the National Institutes of Health’s National Library of Medicine’s PubMed database, there were 3 results for a search of “forest bathing” in 1965 (before that, zero). In 2025 there were 3,096 results. For an easy read of the studies, the Association of Nature & Forest Therapy, which provides training to certify guides, lists studies by impact such as general well-being, cancer, cardiovascular, mental health, immune system, pain, pulmonary disease, sleep disorders, stress burnout, and more. There also are several books written about forest bathing as well as its impact on people’s health.

In Japan, there are more than 60 designated forest therapy trails. It is estimated that one-quarter of the population uses these trails. In some of them, researchers obtain vitals from volunteers before they enter the forest and afterwards. They have found correlations with stress and blood pressure reduction, improved mood, increased energy, improved sleep, increased concentration and increased immune cells in the body.

Here in the United States, there are forest therapy trails although none in the DC metro area. However, one does not have to be on such a trail to experience forest bathing. Paul remembers a forest bathing experience in the rose garden right in front of the Smithsonian Castle with cars whizzing by.

If you have never gone forest bathing, I recommend doing it with a certified guide to see what it is all about. Once you learn the concept, you can just go to your backyard for 20 minutes and still reap the health benefits. For forest bathing events, check out the local public gardens, park systems, and arboreta such as:
U.S. National Arboretum (through the Friends of the National Arboretum)
Hillwood Estate, Museum and Gardens
Green Spring Gardens

Gaura, Whirling Butterflies, or Wand Flowers

Close up showing four petals.

Recently I have been thinking that I would be better off planting southern plants in order for them to better survive this heat in my Zone 7 Northern Virginia garden.  I have several southern beauties that do quite well that I call gaura or whirling butterflies. Technically their name is not gaura anymore. Gaura lindheimeri was reclassified as Oenothera lindheimeri but if you look it up you may find it still called gaura.

These are herbaceous perennials native to Texas and Louisiana. The species grows to about 3 feet tall but really it is 3 feet of wiry stems and small, inch-wide pale white/rose flowers. At the base is a clump of foliage that dies back in the winter.  The thin stems sway back and forth while butterflies try to land on the flowers. The bees are more successful.

Gaura blooming in the front garden

Drought and deer resistant, gaura has bloomed every year for me in full sun with no pests or diseases. I have heard that gaura self-seeds but not in my garden. The species, which can get tall, is wilder looking than the new short cultivars. But since it has long, thin stems, the plant is practically translucent so you can easily tuck it in the garden and not block the view of other plants. There has been a lot of breeding with this plant to introduce compact types, red/burgundy foliage instead of green, and a wider range of flower colors from bright white to rose pink to red.

This plant blooms all summer long, creating a haze of flowers. Hardy to Zone 5, gaura does not need to be coddled, it does not need rich soil or fertilizer. My plants are so old, I don’t even know where I got them. I have enjoyed them so much I have purchased more to put in other parts of the garden.

Close up of ‘Grace’

I highly recommend this drought-tolerant, native plant. It is easy to find in the local nurseries and although it can be grown from seed, it is best to start with a plant. If you don’t have the space try the compact types that could serve as drought resistant, summer container plants.

Baptisia Plants Perform Well in the DC Metro Area

Baptisia ‘Lemon Meringue’ flowers up close

Blooming now in my garden are several baptisia plants, also called false indigo. Baptisia is a shrub-like plant that does well in our hot and humid summers. Recent breeding efforts have expanded the range of flower colors creating a new look for an old favorite.

I have two Lemon Meringue and two Dutch Chocolate plants. I purchase them 10 years ago as small plants and now in May, they are about 3 feet tall and blooming. They bloom in April and May and surprisingly make good cut flowers. I cut a few branches for a simple indoor arrangement and they lasted over a week. The blossoms are similar to pea flowers on tall spikes.

Although they look like shrubs in the summer, these plants are herbaceous perennials. In the fall, they produce dark brown pods that rattle and can either be left on the plant or used for dried flower arrangements or crafts. The shrubs die back in the winter and new growth emerges from the base in March.

Baptisia plants are deer resistant, heat and humidity tolerant, and drought tolerant once established.

I highly recommend these plants and if you are looking for top performers, check out Mt. Cuba Center’s 15-page report, Baptisia for the Mid-Atlantic Region. From 2012 to 2015, staff evaluated 46 selections of baptisia including representatives from 11 different species to determine which performs best in the mid-Atlantic region. Over 60 percent of the plants tested receive 4 or 5 stars. Among those, 10 superior cultivars outperformed the rest. Although I did not know it at the time I purchased my plants, they are included in the top ten.

Try growing these plants, which should be easy to find at local garden centers. They will do you proud!

Best Phlox Plants for Mid-Atlantic Gardens

Lavelle phlox

Lavelle

Since I have been living at this house in Northern Virginia, a bed of creeping phlox has bloomed every spring without fail. The plant came with the house and we have been here for 25 years.

Phlox is a very common perennial in the mid-Atlantic area. Many gardeners –as well as butterflies– love the old-fashioned, native plant for its tall stems of summer-blooming pink, purple, or white flowers.  Phlox is actually a large genus comprising more than 60 species native to North America. There is wide variation — some plants are tall, low growing, or groundcovers, while some prefer full sun and others thrive in shady, woodland areas.

This year, before you purchase phlox for your garden, read about the recommended varieties in Mt. Cuba Center’s report. The horticulturists at the Trial Garden, Mt. Cuba Center, Delaware, completed a three-year study from 2015 to 2017. Although the report was published a few years ago, the data is still applicable. Staff tested 94 selections of eight sun-loving species and 43 selections of two shade-loving species.  For the sun lovers, they deliberately tested for resistance to powdery mildew, a fungal infestation of the foliage that creates an unsightly white powder. (This usually does not kill the plant but detracts from its beauty).

Of the sun-loving plants, within the species Phlox paniculata, top performers are ‘Jeana’, ‘Glamour Girl’, ‘Delta Snow’, ‘Lavelle’, ‘Robert Poore’, ‘Dick Weaver’, ‘David’, ‘Ditomdre’ (Coral Cream Drop), ‘Shortwood’, and the hybrid P. x arendsii ‘Babyface’.

Jeana

“Jeana,” according to the report, “is, without a doubt, the best performing phlox from the trial. This cultivar was discovered growing along the Harpeth River near Nashville, Tennessee and named after its discover Jeana Prewitt.”

Interestingly, volunteers who monitored pollinator visitations in the trial garden, noticed that ‘Jeana’s’ pink flowers received 539 visits from butterflies over 2 years. Others phlox flowers received at best 117 and lower.  ‘Lavelle’, second in place, received 117 visits indicating a marked preference for ‘Jeana’.

 

Blue Moon phlox

Blue Moon

Horticulturists also trialed shade-loving woodland phlox (Phlox divaricata) and creeping phlox (Phlox stolonifera). Their report stated that the creeping phlox was easy to grow while the woodland was more difficult. However, they conceded that their initial plants of the woodland may not have been the healthiest. The best performers of woodland phlox are Phlox divaricata and P. divaricata ‘Blue Moon.’ With creeping phlox, best performers are Phlox stolonifera ‘Fran’s Purple’, ‘Home Fires’, ‘Pink Ridge’, and ‘Sherwood Purple’.

Growing Taro, aka Elephant Ears or Colocasia

taro plantsIn March 2024, I purchased a few taro corms in an Asian supermarket when I made my annual trek to purchase the lemongrass and ginger. I potted them up in small containers with drainage holes, watered and put them in the living room. The warmth of the home and the water encouraged them to sprout. In May, I planted them outside in the garden.

Taro, also known as elephant ears (Colocasia esculenta), produces large, 1 to 2 feet long leaves, similar to an elephant’s ear. The entire plant will reach about 2 to 3 feet tall. Mine had green foliage but there are Colocasia cultivars with beautifully colored foliage.

Colocasia plants are tender herbaceous perennials native to Asia. The “root” is called a corm and is used as a food source, much in the same way we use potatoes. The leaves and stems are edible too but nothing should be eaten raw. This plant must be cooked first. The taro was being sold at the Asian supermarket as food but for a few dollars I purchased them to use as ornamental foliage for my garden.taro corms

My plants grew well in 2024. Mine were in afternoon shade in moist but well-drained soil. Our hot and humid summer did not faze them. Because mine were green, they were relatively simple plants but if I were to do it again I would use them in large containers. Their size makes them more suitable as a thriller. Either that or plant many in one area for a more dramatic effect.

Taro is hardy to Zone 8 and although I am in Zone 7, my plants came back in the summer of 2025. I was pleasantly surprised!  I could have dug up the plants in the fall of 2024 to save the corms (like dahlias) but considering how cheap they were, I decided to leave them in the ground. If I had them in a container, I doubt they would have come back in 2025.

Try growing taro in your garden. For just a few dollars, you can grow taro as a thriller in a container or for a tropical vibe in the garden. And don’t forget to get the lemongrass and ginger.

A Holiday Houseplant: Lemon Cypress

lemon cypressAs Christmas approaches, lemon cypress plants emerge, draped in holiday costumes. You have seen these small, yellow evergreens at garden centers and food markets. Wegmans has them in red containers with a single one red ornament. Trader Joe’s has “Grump” trees inspired by Dr. Seuss’ How the Grinch Stole Christmas. The trees are wrapped to droop with a large ornament. Admittedly, these would make great gifts but then what? How do you take care of these live plants?

The lemon cypress is a yellow-colored form of the Monterey cypress (formerly named Cupressus macrocarpa, and now called Hesperocyparis macrocarpa). The ‘Goldcrest’ cultivar is commonly found during the holidays. The foliage will give off a citrus or lemony scent when brushed. In its real life, it is a narrow, columnar evergreen that can grow very large. Here, it can live a dual role of houseplant or outdoor plant in the summer.

As a houseplant, the lemon cypress prefers cool temperatures in the 60s, but as much light as possible. That is hard to do indoors. Also, the humidity indoors in the winter is low so you may have to increase it around the plant. Water when the soil is dry in the top inch.  Make sure the container has drainage holes. You may have to separate the plant from the holiday décor after Christmas and repot the plant in a container with drainage holes and better potting mix. Also, keep in mind that pests such as spider mites, aphids, and mealybugs flourish during the dry winter months.

Outdoors, a lemon cypress plant can eventually grow to 6-10 feet tall and 1-2 feet wide. It can be grown as a specimen, hedge, bonsai, or container plant. If you bought one for the holidays or received one as a gift, keep it indoors until the last spring frost, usually mid-May. Plant either in the ground or in a container.

Lemon cypress prefers cool, moist summers. It should be grown in full sun, but here in the DC area, it may need protection from the afternoon sun when temperatures get in the nineties. Plant in well-drained soil and water well after planting. Continue to water to make sure it has water until established. The lemon cypress is hardy to Zone 7. If you are lucky, you may be able to keep it alive and decorate it yourself for the next holiday season. Happy holidays!

A Gardener’s Holiday Wish List

I always thought it was easy for my family and friends to select gifts for me because I am a gardener. A gardener always “needs” a particular plant or seeds; the latest gardening book; supplies like pruners, snips, and gloves; and all the accoutrements that exist in the gardening world. I thought having the word “gardener’ branded on my forehead meant everyone knew to give me gardening items for the holidays. But recently I learned that non-gardeners may be in a conundrum. They may be mystified – after all what is a secateur? What plant would do well and how many seeds should be bought?

In an effort to help these lost souls, I asked fellow gardeners for gift suggestions for gardeners. I could create my own list, but it would just end up being my wish list for myself.

Here are ideas from fellow gardeners across the country. I especially like Amy Martin’s suggestion of the Clever Fox Gardener’s Journal. I have not heard of this brand before and I know Amy speaks from experience, as she is a local landscape designer with many years of experience.

An accomplished speaker, writer, and radio and podcast host in Massachusetts, C.L. Fornari has published many gardening books. She has several gift suggestions including book recommendations. I have both Carol Michel’s books and Ellen ZachosMythic Plants. Plus, I know Brent and Becky Heath and have ordered from their family-owned, Virginia-based bulb store. Speaking of Carol, earlier this year, she asked fellow garden writers what book impacted their lives, which I have linked here.

In her “Goddess Gardener’s Gift Guide for 2025,” California-based writer, author, speaker, and radio personality Cynthia Brian recommends both adult and children’s gardening books as well as tools. I also can endorse the CobraHead Weeder & Cultivator which I have. The sharp, pick-like end is very good at tearing up weeds.

Based in Colorado, Randy Schultz, well known gardener, writer, author, and founder of the Home, Garden, and Homestead website just published best gardening gifts for the holidays on the website.  I especially liked the Changshou kumquat tree from Logee’s Plants which I could probably grow here if I brought it indoors in the winter. Logee’s Plants sells indoor tropical plants, including edible and unusual plants. I highly recommend visiting their website.

All of these are good suggestions. I am going to make a cup of hot cocoa and modify my list before I mail it to the North Pole. Happy Holidays!

Mosquito-Repelling Plant Myths

There is a common myth that planting lemongrass (Cymbopogon citratus) in the garden will prevent mosquitoes. Lemongrass is a stunning specimen plant and a fantastic culinary herb, but it will not repel those nasty pests. Although it is true that the foliage contains an essential oil which mosquitoes do not like, a person would have to cut open or bruise the foliage to release the oil and apply the oil all over the skin. Lemongrass has very sharp foliage and applying an oil directly on the skin could cause a reaction. Plus, you would have to cover every exposed inch, including the face, as mosquitoes can find an unprotected spot the size of a dime.

So don’t be fooled into purchasing lemongrass in order to have a pleasant, insect-free party on the patio. Likewise, don’t think that “mosquito” plant, a type of scented geranium (Pelargonium graveolens citrosa), peppermint (Mentha x piperita), lavender (Lavandula spp.), catnip (Nepeta cataria), citronella lemon balm (Melissa officinalis citronella), and lemon eucalyptus (Corymbia citriodora) will do the trick. All of these may have an essential oil in the foliage that mosquitoes find repellant, but the leaves would have to be crushed, wiped all over the body, and potentially cause a skin reaction.

It is best to spray with DEET or other EPA-approved repellants that have been formulated for use on bare skin. Another alternative is to wear permethrin treated clothing (but even then you would still have to apply something on body parts not covered by clothing). Here are more tips to control mosquitoes on your property.

Mukgenia: A Crimson Pig Plant for the Garden

Last year, when I attended the Fling at Puget Sound, I received a plant that was new to me from Little Prince Plants (thank you Little Prince for donating many plants to the Fling attendees). I dutifully packed it in my suitcase and planted it in my Virginia garden as soon as I got home. I am happy to announce it survived both the trip and this past winter. Although it is hardy to Zone 5, you just never know. Now in April the foliage is emerging, promising great things to come.

Developed by Terra Nova Nurseries, Mukgenia NOVA® ‘Flame’ is an intergeneric cross between two genera in the Saxifrage family: Mukdenia and Bergenia. The name “mukgenia” comes from “muk” from Mukdenia and “genia” from Bergenia.

Bergenia is an herbaceous perennial that you may know as pigsqueak. It thrives in shady conditions, in moist soil high organic matter. These plants are known for their large glossy leaves; spring-blooming, pink flowers; and dramatic red/bronze fall color. Rubbing the leaves together produces the sound of a pig squealing.

Mukdenia ‘Crimson Fans’ also is an herbaceous perennial known for large, ragged leaves that look like half the leaves were dipped in red paint. It too blooms white flowers in the spring but not as pretty as Bergenia. However, its fall color is gorgeous – a solid mahogany red plant.

Mukgenia NOVA ‘Flame’ combines the pink flowers of Bergenia with the interesting foliage of Mukdenia ‘Crimson Fans.’ The foliage is ragged, as if the edges were torn by hand. Many leaves have dark red edges. Hardy to zone 4, this clumping plant grows to about 8 inches tall, blooms in the spring and then exhibits great red fall color. Although the foliage is thicker than Mukdenia, this is not a drought resistant plant. It likes shade, and moist but well drained soil high in organic matter.

I am looking forward to this new addition to the garden but does anyone know if it still squeals like a pig?

Happy St. Patrick’s Day! Enjoy Your Shamrock Plants

Happy St. Patrick’s Day! Although the shamrock plant looks like a three-leaf clover it is actually a species of Oxalis. These are commonly sold as St. Patrick’s Day gift plants but they make great houseplants and garden plants.

The plants can have either green or burgundy foliage. The small flowers rise high above the leaves with five white or pink to white petals. Most people grow them as houseplants but they can be grown outdoors in the summer here in Virginia. Because they are small, it is best to grow them in containers (off the ground level) for better viewing. These are great to plant at the base of a large container that has other flowers to hide bare stalks. Or combine a burgundy foliage shamrock with a green plant like lemon verbena in a container for contrast (just eat the lemon verbena, not the shamrock).

Shamrock plants grow from rhizomes called pips which can rot if overwatered so it is best to let the soil dry out a little between watering. Eventually the plant will go through a dormant period and produce more pips that can be dug up for more plants in the fall.

In the house, the plant is best grown in indirect light with cool temperatures. Usually it is only after you purchase the plant that you learn of its charm. The leaves move up and down every day. In the daytime, at maximum light, the leaves are horizontal or open. By nightfall, when light levels are reduced, the leaves bend down almost as if the plant is wilting. Don’t worry, this is normal and does not mean that you have to water.

Shamrocks are beautiful houseplants but there is one caveat: they do not combine well with pets. Oxalis contains a high level of oxalic acid, which can be poisonous.
