Queen Anne's Lace: Lovely Wildflower or Alien Invader?

Queen Anne's Lace
This delicate Queen Anne's lace shows the reddish purple center spot which lures flying insects.

There is a white flower whose large target-like blossoms are liberally lacing the countryside in all directions. Few weedy flowers are as well known in the Northern Hemisphere as the Queen Anne’s lace. On the one hand their intricate blossoms are beauty to behold, while on the other they are nothing more than pernicious invasive weeds that do not belong in gardens or cultivated fields.

Its presence, dating back thousands of years, is reflected in its genus name of Daucus, which is what it was called in ancient Greece. You are correct if you think that its leaves resemble those of the carrots growing in your garden. Its species name is Carota (ca-ROE-ta), the old generic name for carrot. Many people call it the wild carrot, an accurate title in that it was the wild progenitor of our garden carrots of today.

Some trace its arrival in America to easterners who brought the plants from Europe to be introduced into their Victorian gardens. Believe me, they have found their way into our garden all by themselves – many of them! One flower gardener, who made the terrible mistake of adding a few to her garden as tall accent plants, eventually claimed that they were far worse than house guests who overstay their welcome. In most instances house guests will eventually leave but, unlike the Queen Anne’s lace, they don’t leave their children behind.

Crab spider
A crab spider waits patiently on a Queen Anne's lace blossom for its insect meal to arrive.

As an old saying goes, "Give it an inch and it will take a mile." It is a prodigious seed producer, grows in the poorest of soil, and requires no attention whatsoever. Then, as though doubling its chances of survival, it is a biennial. In examining the dry weedy slope east of our house I find hundreds of tiny first-year carrot-like plants, already building up strength in their roots for producing tall, flowering, seed-producing Queen Anne’s lace plants next summer. My firm advice is to not allow this plant to add a touch of elegance to your garden!

The plant is a member of the parsley family, also referred to by botanists as the umbelliferae family, pronounced "um-bel-LIF-er-ee." Its lacy-white umbrella-shaped flower-heads are called umbels. Examine one flower and you will see that the total umbel is comprised of many smaller umbels.

The plant I dissected, particle by particle, contained 56 small umbels. One of those umbels in turn was composed of 42 tiny individual flowers. Undoubtedly you can find a Queen Anne’s lace with at least 2,352 or more very small individual flowers.

The plant’s fern-like leaves are very finely divided with lateral leaflets, such as on an ash leaf, and said to be pinnate. Others are twice-divided and are bipinnate (BY-pin-nate), while those larger leaves at the bottom of the plant are very feathery and are usually divided three times, being tripinnate (TRY-pin-nate).

Next, in order to thoroughly examine a plant, dig up its entire root, wash it off and crush it to obtain its rather distinctive carrot-like odor. Don’t be led into thinking that the roots are good-tasting – in fact you will find them to be quite bitter. A strong word of caution must be added at this point. Beware of look-alikes, especially the poisonous, rash-producing, wild parsnip whose umbel-shaped flowers are yellowish and lack the small purple central florets most Queen Anne’s lace flowers have.

There are botanists who believe that the small, sterile, purplish, central florets found on many of the intricate compound inflorescences of Queen Anne’s lace plants act as decoy flowers whose design in nature is to attract insects which, inadvertently, will become the important pollinators. Strangely many insects will automatically be lured to the dark-colored flower and it is there that we have seen crab or flower spiders patiently waiting, being ambush spiders, for their next meal to arrive.

If the crab spiders have come recently from yellow flowers, such as the common St.Johnswort, they will be light yellow and adorned with faint pink markings. Give them a few days on the white lacy flowers and gradually they will turn white, also with pink markings, to match perfectly the white "umbrellas" with their purple centers, near to where they are waiting for their next victims’ arrival.

It was Queen Anne of Denmark (1577-1619), daughter of King Frederick II of Denmark and Norway, after whom this widespread flower was named. Eventually she became Queen consort of King James I of England. History tells us that there was much inbreeding among the European royalty, a higher-than-normal degree of consanguinity, which brought about its share of hemophiliacs, characterized by excessive bleeding.

The storytellers inform us that Queen Anne pricked her finger with a needle while making lace and bled to death and that the lovely Queen Anne’s lace flower came into existence as a reminder of how Queen Anne met her fate.

Here is a plant that can be a poet’s delight, an inspiration for the artist, an absolute mecca of a multitude of learning possibilities for good teachers and their students, the ideal source for studying and photographing insects, or an ecologically invasive pest to gardeners and farmers. The choice is yours!

Let’s face it, even though the vast majority of these abundant and attractive weeds are "alien invaders" so were many of our cherished ancestors!
