Lambkill
Kalmia augustifolia · Ericaceae
How it looks
Lambkill (Kalmia) is an evergreen shrub with narrow, long, leathery leaves arranged opposite one another. In late spring, pink-to-purple cup-shaped flowers cluster at the branch tips. Height 20 in to 5 ft (50 cm–1.5 m), with a low, spreading form.
Dangerous — heart toxicity
All parts of this plant 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
Lambkill 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.
