Lagerstroemia speciosa: Queens Crape Myrtle1

Edward F. Gilman, Dennis G. Watson, Ryan W. Klein, Andrew K. Koeser, Deborah R. Hilbert, and Drew C. McLean 2


This is one of only a few deciduous trees which grow in tropical and subtropical areas of the country. A profusion of large, three-inch wide, bright pink to lavender blooms appear in dense, foot-long, terminal panicles from June to July, making queen's crape myrtle a spectacular specimen or street tree. This large, upright rounded, deciduous tree is clothed with 4 to 14-inch-long, dark green, oblong, leathery leaves which turn attractively red before falling in winter. Queen's crape myrtle can reach 30 to 60 feet in height and a spread of 30 to 40 feet. The attractive bark is smooth, mottled and peeling. In India, the wood is used for railroad ties and construction. The bark is thin and easily injured.

Use and Management

Queen's crape myrtle will grow in full sun on a wide range of well-drained soils but is not salt-tolerant. Where there are no overhead restrictions, this makes a nice large street tree due to the upright-spreading habit of growth. This reduces the regular pruning needed to remove lower drooping branches on some other trees. However, when the trees are young, some lower branches will need to be removed for street tree planting to create clearance for passage of pedestrians and vehicles. The tree should tolerate storms well having hard wood with flexible branches, as long as they are well spaced along the trunk and not clumped together growing from one point on the trunk. Plants should be watered faithfully and protected from frost. Not a tree to plant and forget, queen's crape myrtle appreciates regular fertilization or leaves become chlorotic. It will tolerate alkaline soil.

Propagation is by cuttings, division of root suckers, or by seed which germinate readily. Plants will flower the second year from seed. There are other species of tropical Lagerstroemia, some available in selected nurseries.


Aphids and scale, followed by sooty mold.


No diseases are of major concern.
