Winter Savory: A Beneficial Herb for the Garden

Winter savory blossom, up close

Winter savory (Satureja montana) has been a member of my Virginia garden for a number of years.  My plant is in full sun, in poor soil, and has never been bothered by diseases or deer. Hardy to zone 6, my winter savory has grown to be a short, woody shrub, about a foot tall. The green, needle-like foliage is less than an inch long, with many leaves per branch. Now, in February, the leaves are bronze-purple because of the cold. In the summer, the green plant is covered in small, white flowers, attracting beneficial insects and pollinators, including bees.

Winter savory in winter

I like winter savory for two reasons. It retains its leaves and transforms color in the winter, adding interest to the garden. It is a great pollinator plant, which I need for my summer veggies. Although winter savory foliage can be used for cooking, I tend to leave it alone and let it flower. For the kitchen, I grow its cousin, summer savory (Satureja hortensis). Summer savory is an annual herbaceous plant with similar foliage only a bit longer and not as woody. It is easy to grow from seed once frost has passed. Since I harvest the leaves for cooking I tend to disrupts summer savory’s ability to flower. Although it produces similarly shaped flowers, it is not grown for its flowers.

Savories are very old herbs, used for more than 2,000 years. Interestingly, there are two theories for the “Satureja” name. One is that it is a derivative of za’atar, a general name of eastern Mediterranean herbs with oregano-like aroma. The other theory is that Pliny the Elder, a Roman author, called the plant “satureia,” meaning “of the satyrs.” The satyrs are the mythical half horse/half man animals who eat plants such as savory to achieve a great level of sexual stamina (thought you might find that handy since Valentine’s Day is this week).

Today, savory is known as the bean herb. Chefs tend to use the summer savory leaves to flavor beans, stews, tomato-based sauces, vinegars, stuffing mixtures, vegetables, meat marinades, chicken salad, and soups. They are an ingredient in herbes de Provence and fines herbs. They blend well with other herbs such as parsley, marjoram, oregano, basil, rosemary, and thyme. Both summer and winter savory have thymol and carvacrol, the characteristic aromas of oregano and thyme. However, winter savory is more pungent and has been used as a pepper substitute.

This summer, buy both and grow them for the garden, the pollinators, and for zest in your meals!

Anise Hyssop: Culinary Herb of the Year

anise hyssop at the National Herb Garden in July

The International Herb Association has named the Agastache genus as the 2019 Herb of the Year. There are about 20 species, all native to North America. Of the agastache plants, anise hyssop (Agastache foeniculum) is the most well-known for culinary uses in Europe and America.

Anise hyssop is an herbaceous perennial hardy to zone 4. It is a short-lived perennial but it self-seeds and spreads a bit by rhizomes. In March, the leaves emerge with a purple hue. As the plant grows the leaves become green (although there is a golden cultivar). A member of the mint family (Lamiaceae), the leaves have scalloped edges and look like catnip leaves. Anise hyssop grows a few feet tall and about one foot wide. In the summer, there are small lavender-blue flowers on 4 to 6-inch terminal spikes, creating fuzzy wands. The flowers attract beneficial pollinators, including butterflies and hummingbirds. Because the foliage is so fragrant, deer do not seem interested.

Anise hyssop is a full sun to part shade plant tolerating a wide range of soils in a well-drained site. In addition to its culinary use, anise hyssop is an asset in the garden as an ornamental. It provides contrast to orange and yellow flowers and complements purple foliage plants.

Anise hyssop is harvested for its leaves as well as its flowers. Although the aroma is categorized as anise or licorice, some might say anise with a touch of basil or anise with a touch of tarragon. The most common use of the leaves is tea but you can also add the leaves to lamb or pork dishes, to the milk for making ice cream, sugar syrups and/or sugar syrups for cough drops, cocktails, honey, butter cookies, and sugar to make flavored sugar. The leaves dry well, retaining their taste and fragrance.

Use the flowers as a garnish for desserts, add to a salad, or add to a beverage such as ice tea. The flowers also dry well, retaining their color and aroma.

You can find small plants in the nursery in the spring or you can grow anise hyssop from seed. Sow the seed indoors under lights in order to transplant outside after the last frost or sow outside in the summer. Anise hyssop can also be propagated by root division.

This summer, grow anise hyssop in your garden for beauty as well as flavor.

Parsley: A Landscape Edible

Parsley is one of those easy to grow landscape edibles that adds beauty to your garden and flavor to your cooking.

Here in Northern Virginia, parsley can stay green above ground in the winter.

Parsley is a biennial, it produces foliage the first year and flowers the second year. I have set aside a small area in the ground I call the parsley patch. There are enough plants so that some are in the first year (when I want to harvest foliage for the kitchen) and some are in the second year (when I want them to flower, develop seed, and drop the seed to the ground to create new plants for next year). Just for extra luck, I also scatter seeds every spring. This way I can harvest fresh parsley year round.

Parsley likes organic matter, moisture, and morning sun or dappled sun. My plants are in the ground but parsley can be grown in containers and window boxes for the summer. I grow flat leaf or Italian parsley, which is best for culinary purposes. There is a curly leaf type that is best used as a garnish.

To harvest parsley, cut outer, older leaves at the base, leaving the core or inner, younger leaves.  Cut with scissors (don’t pull) and put in a large bowl of cool water for about 20 minutes (to wash the foliage and drown any bugs). Pat dry and cut the leaves and stems into small pieces with scissors or a knife.

I use parsley for my bean stew, roasted vegetables, roasted potatoes, pasta, and salads. I have used leaves for garnish for holiday dinners and plates of fruit. In addition to its flavor, parsley has high levels of vitamins A, C, and K, plus a high level of chlorophyll that freshens your breath!

New Apple Variety Bred Specifically For Local Pick-Your-Own Orchards

We are in luck, a fresh apple experience is coming our way. University of Maryland has released the first apple variety developed for the mid-Atlantic region called Antietam Blush. Six more varieties will follow, all adapted to the area’s summer heat and humidity, with increased drought and disease resistance. Antietam Blush is the first apple variety bred specifically for this area.  The trees are shorter, thus eliminating the need for ladders, and designed to be picked in October (good for pick your own orchards). The stronger tree architecture makes it easier and less labor intensive to maintain plus this variety is bred to be resistant to the fire blight bacterial disease.  Because the trees are smaller, they can be planted closer together without support, which means more apples can be produced. The apple is blush red, sweet and slightly tart, with a high sugar/high acid fruit content that stores well. Dr. Christopher Walsh, Professor in the Department of Plant Science and Landscape Architecture, College of Agriculture and Natural Resources, University of Maryland, says that Antietam Blush combines the tartness of its parent, Cripps Pink, with the champagne fizz of its grandparent, Gala.

Dr. Walsh and then-graduate assistant Julia Harshman worked on this new kind of apple tree for nearly 30 years. When they started the main university apple breeding programs were at Cornell University, Washington State University, and the University of Minnesota. No one had bred an apple specifically for the mid-Atlantic region.  They recognized the need for an apple tree that would tolerate the hot, humid summer climate. Over time they bred trees to combine a heat tolerant fruit with a tree architecture that reduced the need for hand pruning and ladders. Dr. Walsh received the University’s first ever apple patent for Antietam Blush. Currently, several Maryland growers are growing Antietam Blush, which will be available to the local markets very soon. Check out the University of Maryland’s short video about Antietam Blush.

Grow Your Climate Victory Garden to Help Fight Climate Change

Modeled after the World War II Victory Gardens, gardeners can do their part to fight climate change by planting Climate Victory Gardens. Climate Victory Gardens focus on rebuilding and restoring soil health and employs regenerative agriculture principles at home. Regenerative agriculture is a type of farming that turns dead or degraded dirt into rich, biodiverse soil that acts as a carbon sink. Healthy soil sequesters more carbon than dead dirt. A worldwide switch to regenerative farming could reverse climate change.

Ron Finley and Rosario Dawson teamed up to narrate a video explaining the Climate Victory Garden. Produced by Green America and Kiss the Ground, the video highlights five gardening practices. Together, Ron and Rosario explain the importance of growing food, not using chemicals, composting, keeping the soil covered, and encouraging biodiversity. Although the Climate Victory Garden principles are in alignment with sustainable gardening, Ron explains that sustainable gardening just leaves you in the same place. Regenerative gardening helps reverse climate change by building and restoring soil which can then help pull carbon from the air and store underground.

In order to create a Climate Victory Garden, gardeners are encouraged to commit to the practices mentioned in the video and a few more for a total of eleven. More detailed information on these eleven is on Green America’s website:

  • Grow edible plants
  • Keep soils covered
  • Encourage biodiversity
  • Plant perennials
  • Ditch the chemicals
  • Compost
  • Integrate crops and animals
  • Use people power
  • Rotate plants and crops
  • Get to know my garden

American Heritage: Native Paw Paw Trees

Paw paw flowers in the spring

It’s paw paw season! Paw paws (Asimina triloba) are native trees that bear fruit in August, September, and October. Fruit of cultivated trees look very similar to mangos—green, kidney-shaped, and about 6 inches long and 3 inches wide. They have a variety of common names such as Indiana banana, poor man’s banana, and bandango. When cut in half, the interior reveals a yellow, custard-like pulp with two rows of large seeds. Paw paws can weigh from ½ to 1 pound. Technically a berry, they are the largest North American edible fruit. Paw paws taste like a cross between a banana and a mango with a splash of pineapple. They can be eaten raw or used in ice cream, pudding, smoothies, butter (such as apple butter), baked goods like cookies and pies, and even beer, brandy, and wine!

From Florida to Texas, north to New York, and west to Michigan, Illinois, Iowa, and Nebraska, paw paws are native to 26 states and grow as understory trees in hardwood forests near streams and rivers. In the wild, the trees grow to 15 to 30 feet and sucker, creating colonies. Reminiscent of cucumber magnolias, they have foot-long, dark green leaves. Unlike other fruit trees, paw paw trees are not subject to a high level of pests and diseases.

Paw Paws in American History and Folklore

Paw paw trees are part of American history and folklore. Jamestown colonists wrote about them in the 1600s. John Lawson, an Englishman, described them in his travels in the Carolinas in the 1700s. Danielle Boone enjoyed eating them. Members of the Lewis and Clark expedition ate paw paws for pleasure as well as sustenance. George Washington grew paw paw trees at Mount Vernon and ate the fruit as dessert. Thomas Jefferson grew them and sent seeds to his colleagues in Europe.  William Bartram, a naturalist, described the trees in Bartram’s Travels. His father, John Bartram, a botanist, sent seeds to Europe. During the Civil War, soldiers as well as African American slaves collected the fruit in the wild to supplement their meager diets. There is even a popular folk song called “Way Down Yonder in the Paw Paw Patch” about collecting ripe paws paws from the ground and putting them in a basket.

Paw paw fruit develop in clusters

Finding Paw Paw Trees and Fruit

Currently, Washington DC residents can see paw paw trees in the wild along the C&O Canal and Potomac River and as native plant representatives in public gardens. There are paw paw trees at the Smithsonian Pollinator Garden, next to the National Museum of Natural History, and at the U.S. Botanic Garden’s newly renovated Bartholdi Park and their National Garden’s Regional Garden of Mid-Atlantic Native Plants. 

Although paw paws are part of American heritage, you may not find them in grocery stores. When the fruit is ripe enough to eat, it drops to the ground and is highly perishable. The thin skin bruises easily, discoloring to black. Paw paws are best eaten immediately or preserved by removing and freezing the pulp. You may find them at local farmers markets in peak season and you will definitely find them at paw paw events across the country in the fall.

Growing Paw Paws in the Home Landscape

Paw paw fruits can be eaten raw

“There is a paw paw renaissance now,” said Michael Judd, owner of Ecologia, an edible and ecological landscaping service in Frederick, MD. Author of Edible Landscape with a Permaculture Twist, Michael currently is writing a book about paw paws and hosts an annual paw paw festival that will be on September 22 this year at LongCreek Homestead. “I call the paw paw an edible landscape all-stars because the tree is very attractive, low maintenance, and very fruitful.”

As native, hardy trees, paw paws can be grown in typical suburban plots. “Paw paws grow easily here,” said Michael. “This is paw paw country.” Although they are not self-fertile, that is, there must be two trees to cross pollinate to produce fruit, one can trim the trees to fit in residential properties. Michael recommends growing the trees in full sun, 10 to 12 feet apart, and cutting the central leader back to keep the trees at 8 feet. This shorten stature also makes them easier to harvest the fruit. Therefore, homeowners could have two 8-f00t trees in the yard producing 50 pounds of fruit each year. If full sun is not possible, they can grow in part shade but will produce less fruit.

Paw paw trees have a pyramidal shape

Michael recommends purchasing either a grafted tree, a select seedling, or a specific cultivar. Starting from seed takes years to produce fruit. Also starting from a wild paw paw seed will result in less than desirable fruit. The taste of wild paw paws varies plus the fruit is small with a poor pulp to seed ratio.  Breeders spend years selecting desirable characteristics such as large fruit, a high pulp to seed ratio (more pulp, less seed), and good flavor.

You can’t go wrong planting paw paws. They are native, deer resistant trees that provide fruit and pretty yellow fall color. “Paw paw trees are very ornamental, they have a beautiful pyramidal shape,” explained Michael. “The leaves turn to a beautiful yellow golden color in the fall and when the leaves drop they reveal a tree with nice architecture in the winter.”

Mid-Summer Review of Edibles in my Virginia Garden

August has a way of revealing what is truly successful in my Virginia garden. If the plant can make it through this hot, humid summer, it is a winner in my book. Here are my winners for edibles this summer (click here for my previous article on successful flowers).

Prettiest Vegetable in the Garden

Burpee’s Confetti pepper has green and white foliage

This year, the Burpee Confetti pepper wins the award for prettiest vegetable in my garden. The white and green foliage make this sweet pepper stand out as an ornamental. My plants are about 2 feet high and do not need staking. Although my plants are in the ground, I would recommend Confetti as a container plant because the foliage is so ornamental and the peppers are small enough but colorful. The 2-inch peppers change from green to cream to red. Combined with other edibles and annuals, Confetti could serve as the “thriller” in a container on the deck. Confetti is a snacking pepper, I can eat the entire pepper or slice it for the skillet. Try Confetti next year, you will be surprised at how well it grows and how good it looks and taste.

Most Prolific Vegetable in the Garden

Burpee’s Shimmer tomato plant keeps on producing

I always grow a variety of tomatoes and this year Burpee’s Shimmer wins the award for most prolific tomato plant. Shimmer is an almond-shaped tomato with streaks of green, only about 1 1/2 inches long and 1-inch wide. Shimmer is a plum tomato, a type of paste tomato that is “meaty.” This particular cultivar is sweet too. In my family, we eat them as snacks–you can pop the entire tomato in your mouth–or cut up in green salads. My plants are about 4 feet tall and staked. They produce so much fruit I have to give them away to friends and colleagues. According to the Burpee website, one plant produces 300 to 350 fruit in a season and I believe it! The fruit are in clusters like grapes so it is easier to cut the cluster off, eat the ripe ones and let the unripe ones mature indoors.

Best New Introduction in the Garden

Another prolific plant this year has been the new Proven Winners Amazel basil. Amazel has two features: it is resistant to downy mildew and it is seed sterile. Downy mildew is a fungal disease that destroys the sweet basil plants, making them inedible. There is no cure and once infected the plant has to be removed and destroyed. My plant is quite large, about 2 feet tall and a foot wide. My other sweet basils are small but I have already cut them back for pesto. I have used some leaves in the kitchen but I have not cut the Amazel back yet because I wanted to see how it would perform during these hot, humid days. This is mid-August and I have not detected any disease.

Proven Winners’ Amazel basil is resistant to downy mildew

Unlike other basils which have the sole purpose of flowering and setting seed to ensure survival of the species, Amazel is seed sterile so it does not put its energy into flowering and setting seed. This results in more leaves for a longer time. It actually can flower but will still keep on producing tasty leaves. I highly recommend this basil for both flavor and appearance. The plant is actually quite lush and could be effective as a “thriller” in a large container, surrounded by other herbs or edible flowers.

Most Unusual Edible in the Garden

A few years ago I tried growing roselle (Hibiscus sabdariffa). The plant grew well in large containers but did not flower until very late in the season. Because it bloomed late, only a few of the red fat calyxes could be harvested and then, as a tender perennial, it died in the winter. The plant is about 3 to 4 feet tall and the yellow flowers are about 3-inches wide and look like okra flowers. After the flowers mature, they become enveloped by a large, red, fleshy calyxes. This is ornamental in itself but they are harvested for making tea (the prime ingredient in Red Zinger), jams, jellies, and candy.

Large red calyxes of Thai Red roselle are brewed to make herbal tea

This summer, I planted a variety called Thai Red from Southern Exposure Seed Exchange. What a difference! These plants bloom much earlier, in the beginning of the summer, resulting in many calyxes.  Now, mid-August, I have so many I have to start harvesting and drying them. I use them to make an herbal tea. I have read that they serve as a cranberry substitute so this year I will try using them in scones. Using the Thai Red variety really makes a difference. The plant is not common but it is easy to grow from seed. Next spring, purchase a pack of seed from Southern Exposure Seed Exchange and grow it like a hibiscus plant, full sun, rich soil, plenty of water. Roselle is a great ornamental herb that stands out in a large container or can be grown in the ground.

Basic Culinary Herb Recipes To Try This Summer

This summer, as you cut and harvest your culinary herbs, consider these simple recipes to try. Print this and tape on the inside of your kitchen cabinet (along with the list of herbs you are growing) for easy reference.

Herbal vinegar

tarragon is often used in herb vinegars

Wash one cup of herbs, allow to air dry. Pack leaves (can use stems too) in quart glass jar with wooden spoon. Fill with 3 to 3 ½ cups vinegar to one inch from top. The vinegar should be 5% acidity and best types of vinegar are white or red wine vinegar, rice wine vinegar, or apple cider vinegar. Push down with spoon and bruise leaves. If a metal lid, first cover with plastic wrap, if plastic lid, just close. Store in dark place for 4 to 6 week, shaking every few days. Taste to see if too strong, add more vinegar, or too weak, add more herb. When done, strain leaves out and pour liquid into clean bottles and add a sprig of fresh herb for decoration. Label.

Butter

Wash herbs, let dry. Take a stick of unsalted butter out of the fridge, put in bowl, and let come to room temperature so is soft. Add 2 to 3 tablespoons of the chopped herb, do this to taste. Depending on the leaf, may have to cut into small pieces. Can put in a container to keep in fridge for 2 weeks or roll into saran wrap like a log and freeze for up to 6 months.

Syrup

Put one cup of water and one cup of sugar in a small saucepan. Bring to a simmer. When sugar dissolves, turn off heat, add large handful of herb leaves. Bruise with wooden spoon by smashing against side of pot. Cover and let sit for 30 minutes. When cool, strain leaves out and pour syrup in glass jar and store in fridge for up to 2 weeks.

mint has a variety of uses in the kitchen including sweet syrups

Pesto

Pulverize in the blender 2 cups washed fresh basil, 4 cloves of garlic, (chopped), and ½ cup olive oil until pasty. Add 3/4 cup grated Parmesan cheese, blend again. Can freeze in plastic ice cube trays or flat in plastic bags.

Marinade for meat

rosemary is great for marinades

Depending on the amount of meat can change the quantities but the ratio is 1/4 cup of olive oil, 1 tablespoon of vinegar like a wine vinegar, ¼ cup water, a dash of salt (like soy sauce), a dash of sugar (honey or brown sugar) and about a cup of fresh herb leaves (tear leaves apart if large). Have meat sit in this mixture for at least 30 minutes. Drain and cook meat.

Herb paste

If don’t need pesto, make basil paste to preserve

Can use this as a frozen base for pesto and then add the fresh garlic and Parmesan cheese to the thawed paste or a frozen base for stew or soup. Clean herbs but make sure are completely dry as water and oil do not mix. Blend in the food processor 4 cups of herb leaves to ¼ to 1/3 cup extra virgin olive oil to make a paste. Freeze in bags or plastic ice cube trays. There should be some texture to herb so is a paste and not pureed like liquid. Good with savory herbs such as basil, parsley, and cilantro. If using a “sweet” herb like mints, may want to try sunflower seed oil instead.

Herbs in the Garden Attract Beneficial Insects and Pollinators

small thyme flowers

The herbs in my garden live among the annuals, perennials, vegetables, and shrubs. I have not designed a separate, formal herb garden and now every new herb plant gets tucked in any space I can find. If I remember and have time, I harvest the leaves for teas or for cooking. If I forget or get too busy, the herbs just thrive without me. By summer, they are blooming along with everything else but that’s okay, they still serve a purpose. Even if I didn’t get to harvest them, they are helping the tomatoes, peppers, cucumbers, and beans by attracting beneficial insects.

In addition to attracting pollinators such as bees and butterflies, flowering herbs can attract beneficial insects that will destroy the “bad” bugs. These beneficial insects are either predators, i.e., they eat harmful bugs, or parasites–they lay their eggs in or on the “bad” bug which release larvae that consume the bug.

Many of these beneficial insects are small, thus preferring easily accessible nectar chambers in small herb flowers. In many cases the adult insects need the nectar and pollen of the herb flower while the “babies” or larval stage eat the insects we don’t want in the garden. For example, the larval stage of ladybugs, which look like mini alligators, consume aphids, many beetle larvae, and spider mites, among others. One can attract ladybugs into the garden by planting cilantro, dill, fennel, oregano, thyme, and yarrow so the adult form, the ladybug, can enjoy the pollen.

Lacewings are beautiful slender green insects with translucent wings. Their larvae, known as aphid lions, eat a large number of aphids –thus they have a lion’s appetite — and many beetle larvae to name a few. Lacewings are attracted to angelica, caraway, tansy, yarrow, dill, fennel, and cilantro.

Parasitic wasps are small, non-stinging wasps. There are many types but they all destroy pests by laying eggs inside or on the pest. The eggs hatch to release larvae that consume the prey, eventually killing it. Parasitic wasps will destroy tomato hornworms, bagworms, cabbage worms, Japanese beetles, and squash vine borers. The wasps are attracted to dill, fennel, lemon balm, thyme, yarrow, and cilantro.

Tachinid flies look like houseflies but as parasites, they destroy many kinds of caterpillars, Colorado potato beetles, cucumber beetles, Mexican bean beetles, and Japanese beetles in the same manner as parasitic wasps.  The flies prefer cilantro, dill, fennel, parsley, feverfew, and chamomile.

Hover or syrphid flies look like small wasps because they have yellow bands but they don’t sting. The adults–the flies–will “hover” as they drink nectar from dill, fennel, feverfew, lavender, mint, yarrow, and cilantro flowers. The larvae will consume aphids, cabbage worms, other caterpillars, and mealy bugs.

Herbs also help beneficial insects by providing pollen and nectar when other annuals or perennials are not blooming yet.  For example, cool season herbs such as cilantro and chervil bloom in the spring, providing an early source of pollen to beneficial insects.

Many aromatic, perennial herbs, such as oregano, thyme, and lemon balm, are not eaten by deer and small animals so they become permanent fixtures or “houses” for beneficial insects. Plus herbs are usually planted in bunches or become small shrubs, providing a large “neighborhood” for these insects.

However, despite the number of plants in the garden, these insects will only stay if there is a need, i.e., food for them, and if the surroundings are hospitable. Beneficial insects seek large populations of bad bugs in order to feed their own population. Some beneficial insects wait to lay eggs until there is enough “food” so it may be that the appearance of many aphids is the trigger to have ladybugs increase their own population because they now know there is plenty of “food.” In other words, if there a lot of aphids on bearded irises, wait to see if many ladybugs will arrive on the scene to correct the problem before reaching for an insecticide. Spraying chemicals may kill or alter the balance of beneficial insects. It is now known that plants that are under attack by bad bugs release chemicals which are signals to the particular type of beneficial insect that would be needed to correct the problem. There may be a little or minimal plant damage in order for the beneficial insects to receive the signal to come to that plant.

Herbs can be useful for their flowers as well as their foliage. Planting several different types of herbs in the garden helps protect the rest of the plants against pests.
