Douglas' Waterhemlock Video Stock Footage
The characteristics of water hemlock include its stem which is 0.5–2 meters tall with purplish spots, thick roots, and leaves that are compound pinnate and alternate. The leaflets are usually 5–8 cm long and 1–2 cm wide with jagged edges. The flowers on it are compound umbellate inflorescences with many small, white flowers. There are two seeds for each flower. Seed dispersal for water hemlock seeds comes from means of wind, water, machinery, on clothing, and through transported soil. The seeds germinate in spring, and flowers mature near the end of June and beginning of July. In addition to sprouting new plants from seeds, rootstocks can also product new plants. These are formed in the fall from the basal meristem, and when they detach the following spring, they may form a new plant.
