This spring, we’ve hit the jackpot on steady soaking rains. Our reward is lush green growth, and unwelcomed weeds in the lawn and landscape beds. A roadside weed that we’re seeing quite often is Queen Anne’s Lace, Daucus carota.
The fern-like foliage of Queen Anne’s lace has unexpectedly sprouted in many of our client’s landscape beds. Our Technicians repeatedly hear clients share, “What is this? I’ve never seen this tall weed here before.”
Queen Anne’s Lace seeds can lay dormant in the soil for up to five years, waiting for good sprouting conditions. Steady rain, on multiple days, like we’ve just experienced, percolates down deep into the soil, triggering germination in the buried seeds.
Prolific white flowers, which are produced in the plant’s second year, put out hundreds of tiny seeds. Queen Anne’s Lace has a sweet bloom, similar to the cow parsnip, but much smaller. This plant can become invasive and extremely hard to eradicate due to the strong, deep taproot and the velcro seeds. These hitchhikers move to new locations on pet fur, pant legs, birds and even car tires.
In fact, this plant is the direct ancestor to the commercially grown carrots we eat in our salads. As this fast growing plant gets taller, its leaves shade out smaller plants growing nearby and underneath. The best (and most time consuming) way to remove Queen Anne’s Lace is to carefully pull out each plant, making sure to get the deep taproot.
While it may not look nice in your landscape beds, caterpillars of the large eastern black swallowtail butterflies, think the weed looks and tastes just fine.
