BACCHARIS 'Centennial'

Family

Asteraceae

Botanical Name

BACCHARIS 'Centennial'

Plant Common Name

Centennial Desert Broom, Desert Broom

General Description

This desert-adapted hardy hybrid is a useful shrub for difficult, hot, dry sites. Its parents are the dwarf coyote brush Baccharis pilularis, a native of California and Oregon, and the little known desert broom, B. sarathroides, native to the southwestern United States. A spreading shrub, ‘Centennial’ produces a lush mound of bright green narrow leaves with serrated edges. This is a valuable color in desert regions where most plants bear leaves of muted color or gray. This shrub blooms in spring but the flowers are insignificant. They give way to tufted, tan seed capsules. This plant must have good drainage. In wet conditions the roots may rot. It is known to produce wayward branches that extend beyond the tidy mounds, and these should be cut off immediately to preserve its form.

Reserve ‘Centennnial’ for the most trying conditions along streets and driveways, sun drenched cut slopes and for erosion control on newly graded sloping ground. Integrate it into gardens with blooming xeriscape plants that need lush greenery to fill in the open spaces.
