Poison Hemlock
Conium maculatum

You have probably passed this plant in the wild many times without noticing because it so much resembles other members of the carrot family, especially Queen Anne's Lace (how to tell them apart). Sacred to Hecate and Lilith. This baneful herb is used for magickal work involving astral travel and for purifying ritual swords and knives. The flowers are said to be used in spells to cause impotence in men, and the plant is good for ritually paralyzing a situation. In Europe, it is considered one of the quintessential witching plants and an essential in any witch's garden for hexing. It has been cultivated there since at least the Middle Ages. This deadly poisonous plant is also known as Herb Bennet, Spotted Corobane, Musquash Root, Beaver Poison, Poison Parsley, Spotted Hemlock, Kex, and Kecksies.

How to grow hemlock. This plant is a biennial in very moist areas, which means that the first year it produces a rosette of leaves and develops a root. The second year it sends up flower stalks, blooms, and produces seeds, after which it dies. It can sometimes be perennial or annual (flower first year), however. Seeds will germinate from late summer to early spring and like cool weather. Plant at no warmer than room temperature and barely cover. They should germinate in two weeks. Or sow on Winter Solstice. Transplant to moist, rich soil and full sun. This plant gets 3-10ft/90-300cm tall and blooms all summer. This plant can be invasive.
