Native to tropical areas of the Americas, Duranta (Duranta erecta) or pigeon berry is a frost-tender perennial. This 2- to 15-foot tall flowering shrub is well suited for border areas and living hedges. Clumps of blue, white or lavender colored flowers bloom throughout the growing season. The flowers provide visual interest year-round and attract butterflies and hummingbirds to the garden. Duranta is hardy in U.S. Department of Agriculture plant hardiness zones 10 through 11. In colder areas, grow it as an annual. Plant in full sun for best growth and development. Once planted, this flowering shrub requires only minimal maintenance.

Prune Duranta in late winter or early spring. Use a pair of sharp shears to remove any shoots that grow beyond the desired growing zone. Make cut horizontally across the branches. Wear gloves and protective eyewear to protect against the sharp thorns.
