Poison hemlock, flowering (University of Kentucky Cooperative Extension) |
Last week, we focused on yellow buttercup emerging in fields and pastures. This week, let us take a closer look at another weed that we may be seeing on the farm--poison hemlock (
Conium maculatum).
Although this plant is often seen along roadways, abandoned lots, fence rows, and other non-cropland sites, in more recent years, poison hemlock has expanded into grazed pasture lands and hay fields. The concern not only stems from its invasive nature, but the fact that it is one of the most toxic plants in the world.
Poison hemlock is classified as a biennial that reproduces only by seed. Flowers and new seed are typically produced in late May and June.
