When a plant’s common name includes “weed” many people are hesitant to introduce them into a cultivated garden. But those same weeds can prove to be resilient, hardy, and attractive. Consider Butterfly Weed (Asclepias) or Iron Weed (Vernonia) as two examples. The downside of growing weeds is the possibility that they can be TOO resilient, even bordering on invasive. That is the case with today’s featured plant, Queen Anne’s Lace.
Queen Anne’s Lace (Daucus carota, pronounced DAW-kus kar-OH-tah) has a fat, carrot-like tap root that helps it survive in hot, dry climates. It is quick to spring up in disturbed areas, and is listed as invasive in more than 20 states. Queen Anne’s Lace, also called Wild Carrot, Bee’s Nest or Devil’s Plague, is a biennial. It develops lacy basal foliage in its first year, then blooms second year. Mature plants range from 2-4 feet, with a narrow footprint. It is found in all the lower 48 states, in full sun to part shade.
Queen Anne’s Lace flowers are flat white umbrels up to four inches across with one little purple flower dot in the middle. If you place cut flowers’ stems in colored water (use a few drops of the same vegetable-based colors used in cake icing), the blooms rapidly take up the dye and will change from white to a pastel shade of the selected color. I thought every child had done this at least once, but it appears I was mistaken.
Spent flower heads curl up on the edges into a brown cup-like form that resembles a bird’s nest. They become brittle when dry. Winds break them off their stems, and they tumble about, spreading seeds far and wide. This promiscuous habit, along with their tolerance for any type soil and any pH, means that they spread everywhere unless consistently deadheaded. Cut stems stink but the smell wanes fast enough to enjoy them as cut flowers. I once had to resort to herbicide to rid a perennial bed of these, and have since decided to just enjoy them along roadsides. They are prolific in my area of the southeast. Bees and butterflies love the flowers, and swallowtail butterfly caterpillars eat the foliage.
Parts of the plants can be cooked and eaten in small quantities, but larger amounts are toxic. Contact with leaves and stems can cause dermatitis. Unless one in starving in the wilderness, I see to need to test out the toxicity threshold. If you feel the need to consume, be positive of your plant identification. Queen Anne’s Lace is easily confused with Wild Parsnip and Wild Hemlock. Consuming either of these can be deadly. Wild Hemlock is the plant that killed Socrates. Its stem has purple spots.
Note the single purple flower in the middle. Not every umbrell has this oddity.
