Over the past few years, a couple of poisonous weeds have invaded our natural areas as well as the landscapes.
Poison hemlock...yes, the same poison used on Socrates! Again, a biennial like parsnip, poison hemlock grows 4-10 feet tall, leaves are pinnately compound and fernlike, with white flowers that have five notched petals arranged in an umbel 2-3 inches across. Very similar to Queen Anee’s lace, poison hemlock is distinguished by the purple spots and blotches along the stems. All parts of the poison hemlock are toxic to humans and animals.
Controls for these toxic weeds include handpulling before they go to seed (protect your skin), repeated mowings, or spraying with weed killers in the lawn or Roundup in open areas...and spray when they are smaller in size.
