Orange Day Lily

How it looks
The orange day lily is a perennial with narrow, long sword-shaped leaves growing in a clump from the base and six-petaled trumpet-shaped orange flowers at the tip of the flower stalk. A single bloom lasts only one day, but a new flower opens each day. Height 2 ft to 3 ft (60–100 cm).
Deadly — kidney failure
Orange Day Lily belongs to the same genus as daylilies (Hemerocallis) and causes severe kidney failure in cats. Petals, leaves, and pollen are all deadly.
Guide for parents
Orange Day Lily is in the same genus as the daylily (Hemerocallis), a deadly plant that causes kidney failure in cats. The petals, leaves, and pollen are all dangerous. If it's in the garden, keep it completely separate from your cat's paths. If you suspect ingestion, head to a 24-hour animal hospital right away even if there are no symptoms.
