Mexican heather looks dainty and delicate, but this shrub is actually tough as nails. It grows in densely branched, two-foot-tall mounds of slender stems covered with bright green leaves that are evergreen in frost-free areas. Clusters of tiny flowers—usually in shades of purple, but sometimes in pink or white—bloom all along the stems from spring to fall. Compact, long-blooming and practically problem-free, Mexican heather is a treasure for busy gardeners, in the hot, humid conditions that can quickly stress fussier flowers.
