Duranta, usually a large, fast-growing, multi-stemmed shrub, has several common names and over 17 varieties worldwide.
The branches are often droopy and vinelike, and the stems may have sharp spines. Other common names are Pigeon-berry and Honey drops.
Typically, there are full clusters of fragrant pale-blue lavenders, purple or even white flowers on the ends of the stems, reminding the viewer of wisteria.
Butterflies and hummingbirds love them. Flowers are quickly followed by bunches of golden-orange berries, popular with birds.
Duranta loves full sun most, but tolerates part sun, or part shade.
