Q: I noticed a medium-sized shrub with white-variegated leaves recently that had drooping groups of small purple flowers that were being visited by butterflies, bees, and a hummingbird. Any idea what it was?

A: Sounds like Duranta erecta 'Variegata', common names are "golden dewdrop" and "skyflower". This shrub has arching branches and can grow to 25 ft but is easily pruned much smaller. It likes moderate water and a good amount of sun, where it will bloom off and on most of the year. Some of the leaves, especially those that are mostly white, may burn in hot weather. It will grow happily in some shade but blooms less there.  The leaves and small golden berries are poisonous so you may not want to plant this if you have small children who might be attracted to the fruit.
