American Yew
Taxus canadensis · Taxaceae
How it looks
American Yew is a needle-leaved evergreen shrub with short needles arranged like a comb along the branches. It closely resembles English yew but is lower-growing, with branches spreading sideways and slightly shorter leaves. A distinctive feature is the red cup-shaped aril that forms in autumn.
Deadly — cardiac arrest
The leaves, stems, and seeds (except the red aril) of American Yew contain taxine alkaloids; ingestion can lead to tremors, difficulty breathing, and cardiac arrest.
Guide for parents
American Yew is a conifer often planted as a garden tree or hedge. Keep it away from any space your cat shares. Only the red aril (the fleshy covering around the seed) is non-toxic — the needles, stems, and seeds themselves are all deadly. If you suspect ingestion, go to a 24-hour animal hospital immediately even if symptoms seem mild. Cardiac toxicity can progress suddenly.
