a smorgasbord for hummers
Scarlet bouvardia is a medium-sized shrub (2-3 feet in low desert, up to about 4 feet in a good spot) that will be mostly evergreen in warm location in Tucson. At higher elevations it is deciduous. The bright green, glabrous foliage is attractive and late spring through fall scarlet bundles of tubular flowers spill from the plant pleasing hummingbirds, butterflies, moths, and other nectar-loving insects.
Plant in part shade and water moderately. An occasional pruning will keep plants compact.
Scarlet bouvardia is the sole larval food plant of the Falcon Sphinx Moth, Xylophanes falco which is one of the most spectacular-looking caterpillars in southern Arizona. Look for them in August into September.
