Queen Anne’s Lace


On roadsides those big clusters of white flowers are starting to appear. If we dug them up we would notice a root that looks a little like and smells exactly like a carrot. There’s good reason for that. Queen Anne’s lace (Daucus carota) is the predecessor to domestic carrots and were introduced from Europe in early colonial times.

They are biennials (produce seed in the second year) that can grow four feet tall. Feathery foliage resembles that of carrots and flowers look like white lacy umbrellas. Each flower cluster has a purplish center. Stems are covered with glandular hairs. Roots are thick and don’t branch much. They are what we call taproots.

We find these parsley relatives nearly everywhere. They are invaders of disturbed sites.  Queen Anne’s lace matures very quickly and dominates native species.  Plants are adaptable to a variety of soil conditions and thrive in sun and partial shade.  For centuries people have cultivated this wild carrot for medicinal purposes and it has spread to roadsides and fields outcompeting native plants.

Butterfly enthusiasts like them, because the leaves are a major food source for caterpillars of the Eastern Black Swallowtail butterfly. Other insects visit them as well. Bees drink the nectar, and predatory insects, such as the Green Lacewing, come to Queen Anne’s lace to attack prey, such as aphids.

All plant parts have some type of usage. Roots are edible when young, but once they mature they are only useful as a tea. This tea can treat kidney stones, high cholesterol and intestinal worms, a rather odd combination. The large white inflorescences make great summer cut flowers and are used as filler for floral arrangements. Flowers are also edible and can even be fashioned into jelly.

Seeds have a rather unusual property in that when eaten they inhibit the production of progesterone. This inhibits fetal and ovarian growth. Fertilized eggs will not implant properly without sufficient progesterone. Some cultures have used wild carrot seeds as a female ‘morning after’ contraceptive since biblical times. Very little research has been done on this plant’s use as a contraceptive in this country, but numerous studies have been conducted in China and other places. According to research, a teaspoon of seeds within 12-24 hours is sufficient to block implantation. Seeds must be thoroughly chewed or they are less effective.

Along with individual moral considerations, there are concerns about Queen Anne’s lace collection for internal use. This plant is easily confused with the highly poisonous water hemlock. Socrates succumbed to that one. Water hemlock doesn’t have a hairy stem, the flowers, though white, are quite different and the leaves are coarser. However, from a distance and to the untrained eye they can look alike. For this reason don’t experiment unless you know your botany.

This weed is also a serious threat to those who produce domestic carrot seed. It hybridizes with the desired plants which ruins the seed. Carrot seed producing areas have established safeguards. Trying to market Queen Anne’s lace seed in Washington State will cost you a hefty fine. There are no restrictions here in North Carolina.

About tedmanzer

I grew up in Old Town Maine and got a B.S. at the University of Maine in Plant Sciences/ minor in Botany. From there I moved to West Virginia and earned a M.S. in Agronomy at WVU. I also met my wife there. She grew up in rural WV as the daughter of tenant farmers who raised cattle and hogs. Their lifestyle at times was one of subsistence and I learned a lot from them. I've always been a foraging buff, but combining my formal botanical knowledge with their practical 'Foxfire-type' background opened up my eyes a little more. I now teach agriculture to high school students at Northeastern High School in Elizabeth City, NC. My wife teaches with me and we make a great team. I also write a weekly nature/foraging column for the local paper (dailyadvance.com) and frequently publish articles in several other newspapers in northeastern North Carolina. I also have written several Christian nature/adventure novels that I plan to publish eventually. One is a five book family saga I call the 'Forgotten Virtues' series. In the first book, Never Alone, a young boy comes of age after his father dies in a plane crash, and he has to make it alone. Never Alone is now available in paperback, Kindle and Nook. The second book, Strange Courage, takes Carl from his High School graduation to his recovery from a nasty divorce. The third book, Second Chances, takes Carl from his ex-wife's death and the custody of his son to his heroic death at age 59. The fourth book, Promises Kept, depicts how his grandchildren react and adjust to his death. In the final book, Grandfather's Way, his youngest and most timid granddaughter emerges from the shadow of her overachieving family and accomplishes more in four months than most do in a lifetime. I use many foraging references with a lot of the plants I profile in these articles in those books.

  1. this is a intersting flower because it looks like a little white bush but smells like carrots

  2. i believe the use of this plant for females would be a very good thing for the us to study on

  3. amandawensel says:

    why is it you can only eat the roots when they are young but when they get older you can only use it in tea?

  4. Never would of thought this plant would be used for medical purposes

  5. i thinkthis plant is very pretty, but also i like the fact that it can be used for medical puposes also.
