Purple Blooming Anise Hyssop

anise hyssop at the National Herb Garden in July

Anise hyssop (Agastache foeniculum) is blooming now in the summer. A native, herbaceous perennial hardy to zone 4, this plant is short-lived but 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 purple-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 are not interested.

Anise hyssop is a full sun to part shade plant tolerating a wide range of soils in a well-drained site. The purple-blue flowers provide contrast to orange and yellow flowers and complement purple foliage plants.

Anise hyssop can also be used as a culinary or tea herb. It 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 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.

Flowers are edible and can be used as a garnish for desserts, added to a salad, or added 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 directly outside in the summer. Anise hyssop can be propagated by root division.

Anise hyssop is a great garden plant — it provides color in the summer, supports pollinators, and can be used for making tea or to add flavor and color to meals.

Cool Season, Hardy Annuals for Spring Flowers

snapdragons

Now is the time to plant cool season, hardy annuals. Annual plants grow and die in one season. Usually we think of the warm season annuals (i.e., summer) such as marigolds and petunias. However, cool season, hardy annuals are started in the fall, don’t mind the winter, and bloom during the cool spring months before summer.  Typically these are started from seed now and planted in the fall before our first frost in late October.

Evening Bloomers: Four O’ Clocks

A few years ago my family visited Monticello in the summer. I was struck by how large Thomas Jefferson’s four o’ clocks (Mirabilis jalapa) were compared to mine. I also liked the fact that it was a plant he grew and could still be grown today. Four o’ clocks are heirloom, perennial plants that bloom in the summer. Continue reading

Flowers for the Evening: Four O’ Clocks

A few years ago my family visited Monticello in the summer. I was struck by how large Thomas Jefferson’s four o’ clocks (Mirabilis jalapa) were compared to mine. I also liked the fact that it was a plant he grew and wrote about in his journal. These heirloom flowers are still grown today.

Although I had a few small plants in dry, lean soil in full sun, I was inspired to start new plants from seed. I planted them in very rich soil, in an area of the garden that received morning sun and afternoon shade. They thrived and grew to be about 2 feet tall with light green leaves and many yellow or pink blossoms.

Although they are named for opening at 4:00 pm, mine never do. The blossoms are sensitive to light and temperature and prefer to open when the evening cools down, closer to 7:00 pm in my garden. They stay open all night long. In the fall, they develop large black seeds that are very easy to pick and save.

Flower colors come in pink, white, red, yellow, magenta, or mixed, liked speckled. They are tender perennials which means they will grow as perennials in the south. In my zone 7 garden, they should grow as annuals but mine must be in a special micro-climate because mine come back every year.  For people who are north of me, they can try to dig and save the tubers for next year, or start new seed next year. I have a friend who says they are considered aggressive in southern Virginia but I have not had any issues with mine. I heard a horticulturist at a public garden in Atlanta, GA, say that they grow them for the evening visitors, who come to walk the gardens when the temperatures have cooled down.

Four o’ clocks were cultivated and selected for various colors by the Aztecs prior to the Spanish Conquest. They were then introduced to Spain and England and were in cultivation in Europe for about 200 years before Linnaeus first described the species in 1753. Thomas Jefferson received his from France. In July 1767, he noted in his journal “Mirabilis just opened, very clever.”

Try these heirloom plants for an evening garden. The seed are very easy to save so you may see some at seed swaps but if not, try these seed companies.

May Is Dahlia Planting Time

Mother’s Day signals the time to plant dahlias. Like chrysanthemums, many people associate dahlias with the fall but dahlias can bloom from the beginning of summer to frost. Dahlia flowers are available in a wide range of sizes, colors, and shapes. Each bloom can be 2 inches across to more than 10 inches, in all colors except blue. Plants can reach one to 6 feet tall. Some plants have beautiful dark foliage instead of green leaves. Although there are 40 plus species there are thousands of cultivars. In addition, there are numerous forms such as the single, peony, anemone, collerette, star or single orchid, double orchid, cactus, waterlily, ball, and pompom. Continue reading

A Little Patch of Wildflowers

wildflowersThis spring I had an opportunity to create a wildflower meadow on my property. It is rare to have a blank slate to be able to start a wildflower meadow: an area with good soil and no plants, including no weeds. I was inspired by Mike Lizotte who showed photos and gave step by step instructions on Instagram. Owner of American Meadows, an online seed company, Mike wrote a book called Mini Meadows: Grow a Little Patch of Colorful Flowers Anywhere Around Your Yard. He shows how easy it is to sow wildflower seeds and grow a patch of beautiful flowers for the summer. Continue reading

Honesty, Money, and Sincerity: What More Could You Want in a Plant?

Some plants provide beauty in the spring and then step off stage, only to be forgotten until next spring. Others provide beauty in the spring, come back with an encore in the fall, and stay with us all winter long. The silver dollar plant (Lunaria annua) is the latter, a plant that keeps coming back to center stage. These are blooming now in April in the Washington DC area.

National Plant a Flower Day

Today is National Plant a Flower Day. I always have flowers in my garden. Before this pandemic, I used to cut the flowers and bring them to my office. I am no flower arranger, I just put the zinnias, marigolds, and cosmos in a vase on my desk. My colleagues loved them. Invariably they would smile and strike up a conversation. Some would be brave enough to ask me to bring flowers for them while others were inspired to bring flowers of their own into the office. Continue reading

Flowering Tobacco Plants for Deer-Resistant Flowers

flowerThis past weekend I visited Green Spring Gardens in Alexandria, VA. There was plenty to see – quite a lot of plants were blooming but there were also plants with red berries, or beautiful foliage, or bright stems. One plant that stood out for me was the flowering tobacco. The large leaves were vibrant green and some plants still had flowers. Continue reading
