Landscape Use: In Phoenix, fire bush is used almost exclusively as a flowering accent shrub for oasis and mesic plantings.

Form & Character: Rounded, tender, upright, cheerful, festive, tropical.

Growth Habit: In Phoenix, fire bush is mostly herbaceous, moderately upright and spreading, 3 to 5 feet in height with equal spread. in more tropical climates, fire bush grows large into a "fire tree".

Foliage/Texture: Whorled foliage is elliptic to oval, about 6 inches long. Abaxial leaf surfaces (underneath) are gray-pubescent, leaf venation and petioloes are reddish, foliage turns nearlt completely reddish during winter; medium texture.

Flowers & Fruits: Flowers arrayed in terminal clusters called cymes, mostly showy orange to scarlet or crimson, collora tubular, elongated; fruits are black and berrylike.

Seasonal Color: Flowers most of the year.

Temperature: Surprisingly tolerant of Phoenix desert climate conditions (this means it's surprisingly tough)....except for afternoon summer western exposures. Fire bush will 'burn up' under these conditions!

Light: Full sun to partial shade, avoid western exposures and reflected light.

Soil: Tolerant of most desert soils but prefers a well-drained soil but with moderate to high organic matter content.

Watering: In Phoenix, fire bush requires regular supplemental irrigations especially during the summer months to survive.

Pruning: Lightly head back only occasionally. Not unexpectantly, the horticultural clods of Phoenix relish the opportunity to shear fire bush into a "fire bowling ball".

Propagation: Softwwood stem cuttings, seed

Disease and pests: Relatively pest free

Additional comments: Fire bush is a cheerful moderate sized herbaceous landscape shrub that provides floral accent during much of the year and strongly attracts hummingbirds. Firebush growing as a perennial in landscapes in Phoenix always amazes me as I would otherwise think that it would not be able to withstand the intense summer heat of desert Southwest - but alas, it's a tougher plant than one would glean from it's delicate appearance. The fruit have a refreshing, acidic taste and are also edible by humans; in Mexico, they are made into a fermented drink and fruit extracts are known to contain several active phytochemicals which have antibacterial and antifungal properties.

There are a myriad of cultivated selctions based on variations in growth habit and flower colors. The cultivar 'Compacta' grows to only 3 to 4 feet tall in Phoenix.
