Abstract
A new and distinct variety of Lagerstroemia indica , commonly known as crapemyrtle, named ‘Whit XI’, particularly distinguished by having a unique complex of highly modified sepals on a network of large, loose panicle-like structures. The plant does not produce flowers. The leaves are simple, alternate with a smooth margin, typical of the species. Young leaves emerge slightly crimson-green, maturing to dark green. Inflorescences are comprised of a network of irregular stem structures terminating in highly modified panicles with highly modified sepals, at first light purple in color, darkening with age to a darker purple and finally to brown. The inflorescences grow in a network over the surface of the plant and appear and function somewhat like normal flowers. As the modified sepals age they turn brown, but at the same time the panicle continues to grow slowly, producing new sepals light purple in color, which continues the appearance of flowering.
