From the mixed forests and low mountain slopes of China comes this modest crape myrtle species, three to four feet of multi-branched, leathery-leafed determination that rarely appears in cultivation for its own sake. Its flowers, tubular and reddish-pink, measure three to seven inches and open in spring, a brief performance that points toward its greater contribution: the genes it passes to a generation of hardier, more garden-worthy cultivars. Without Lagerstroemia limii in the family tree, cold-climate gardeners would have far fewer options.

In zones 7 and 8, the plant itself is worth growing for the same reasons it matters to breeders: it tolerates drought once established and does not sulk in average, well-drained soil. Full sun is essential, and the soil should be lean enough to push it toward flowers rather than foliage. Water deeply and infrequently during dry periods, keeping moisture away from the leaves. Winter mulch gives it comfort at the cooler edge of its range.
