Andromeda Japonica
Pieris japonica · Ericaceae
How it looks
Andromeda japonica is an evergreen shrub in the heath family (Ericaceae), with narrow, long, leathery leaves clustered at the branch tips. In early spring, small white-to-pink bell-shaped flowers hang in clusters at the branch ends. Height 3–10 ft (1–3 m), with new leaves that take on a reddish tint.
Dangerous — heart toxicity
All parts of Andromeda Japonica contain grayanotoxins; even a small amount can trigger vomiting, drooling, and low blood pressure, which may progress to heart arrhythmias and coma.
Guide for parents
Andromeda Japonica is in the rhododendron family, and everything from its leaves and flowers to its nectar is dangerous. Don't bring it into a space you share with your cat. If you suspect ingestion, head to a 24-hour animal hospital right away even if the symptoms look mild. Cardiac effects can show up late, so it's a race against time. If you grow it on a balcony or in the garden, keep it completely separate from your cat's paths, and make a habit of clearing fallen flowers within the same day.
