Bouvardia ternifolia

Bouvardia ternifolia, the firecracker bush, is a shrub widespread across much of Mexico, the range extending south into Honduras and north into the southwestern United States (Arizona, New Mexico and Texas).

Bouvardia ternifolia is a shrub up to 120 cm (4 feet) tall. It has dark green, narrowly egg-shaped leaves. Flowers are speculacular: long, tubular, bright scarlet, up to 10 cm (2 inches) long, in clusters at the ends of the branches. Hummingbirds frequently imbibe the nectar from the blooms.

Bouvardia ternifolia is widely cultivated as an ornamental because of its showy flowers. It contains Bouvardin which has demonstrated certain anti-cancerous activities.
