Flowers: A beautiful bright pink color, occurring in clusters of about 10-30, each about ⅜-½" (9.5-12 mm) across.

Fruits: Fruits are light brown, small capsules with five sections.

Edibility: Poisonous This plant is highly toxic to sheep as well as people, and can be fatal to either. Toxic ingredients include andromedotoxin and arbutin.
