The Canadian anemone is also found throughout the northern US, except west of the Rocky Mountains.
Identification: These members of the buttercup family have flowers that look
a bit like white buttercups, with pale yellow centers. They reach up to 9-24″ (22-60 cm) in height. Each stem is hairy, and has a single
group of 3- to 5-parted leaves. Leaves near the base are deeply divided. Each flower is 1-1½″ (2.5-3.8 cm)
in diameter, with five white petals (well, sepals that look like petals). Flowers occur in groups
of one to three. Fruits are achenes—that is, the fruit encloses a single large seed. They are
about ⅛-3/16″ (4-6 mm) in size.
Edibility: Poisonous. Symptoms: Inflammation and blistering
upon contact with fresh sap; irritation and pain in the mouth, vomiting and diarrhea following ingestion.
