The crape myrtle (Lagerstroemia indica) is a deciduous flowering tree native to Asia that has become a beloved landscape staple across the southern United States, including Texas. With its vibrant blooms, graceful form, and adaptability to a wide range of growing conditions, the crape myrtle has secured its place as one of the most popular ornamental trees in the region.
Crape Myrtle Botany
Botanical Classification
The crape myrtle belongs to the genus Lagerstroemia, which is part of the Lythraceae family. This genus contains over 50 species of trees and shrubs, with the crape myrtle being the most widely cultivated variety. The specific epithet indica refers to the tree’s origins in India and neighboring regions of Asia.
Morphological Characteristics
Crape myrtles are deciduous trees or large shrubs, typically growing 15-30 feet tall and wide. Their smooth, exfoliating bark reveals beautiful mottled patterns in shades of gray, tan, and cinnamon. The leaves are simple, oblong to elliptical in shape, with a lustrous green color that turns brilliant shades of red, orange, and purple in the fall.
The defining feature of the crape myrtle is its spectacular summer blooms. Clusters of delicate, crepe-like flowers in a wide range of colors, including white, pink, purple, red, and even lavender, adorn the tree from mid-summer through early fall. Each individual flower measures 1-2 inches across, with ruffled, tissue-paper-like petals.
Growth Habits
Crape myrtles are known for their adaptability and fast growth rate. They thrive in USDA Hardiness Zones 7-10, making them well-suited for the warm, humid climate of Texas and the surrounding region. These trees prefer full sun exposure and well-drained, slightly acidic soil, but can tolerate a wide range of soil types and pH levels.
In their native habitat, crape myrtles can grow into large, multi-trunked specimens, but in cultivated landscapes, they are often pruned and trained into single-trunked trees or shrubs. Their natural growth habit is upright and vase-shaped, with a tendency to develop a strong central leader and graceful, arching branches.
Crape Myrtle Cultivation
Planting and Care
Crape myrtles are relatively low-maintenance trees that can be successfully grown from seed, cuttings, or nursery-grown specimens. When planting, it is important to select a location with ample sunlight and well-drained soil. Amending the planting hole with compost or other organic matter can help ensure the tree’s establishment and long-term health.
Regular watering is crucial, especially during the first year after planting, to help the tree develop a robust root system. Once established, crape myrtles are drought-tolerant and can thrive with minimal supplemental irrigation. Fertilizing in early spring can promote vigorous growth and vibrant blooms.
Pruning and Maintenance
Proper pruning is key to maintaining the crape myrtle’s natural form and encouraging abundant flowering. Pruning should be done in late winter or early spring, before new growth emerges. This typically involves removing suckers, crossing or rubbing branches, and thinning the interior to create an open, vase-shaped canopy.
Mature crape myrtles may require more extensive pruning to maintain their size and shape. Some gardeners opt for the controversial “crape murder” technique, which involves severely cutting back the tree’s branches each year. However, this harsh pruning can damage the tree’s structure and limit its flowering potential. A more gentle, selective approach is generally recommended.
Cultivar Varieties
Over the years, breeders have developed numerous cultivars of the crape myrtle, each with unique characteristics. Some popular varieties include ‘Natchez’ (white flowers), ‘Tuscarora’ (coral-pink flowers), ‘Muskogee’ (lavender flowers), and ‘Dynamite’ (red flowers). These cultivars vary in their mature size, bloom color, and growth habits, allowing gardeners to choose the perfect crape myrtle for their landscape needs.
Crape Myrtle Landscape Uses
Ornamental Features
The crape myrtle’s showy blooms, attractive bark, and vibrant fall foliage make it a beloved ornamental tree. Its versatility allows it to be used in a variety of landscape applications, from specimen plantings to mass plantings, borders, and hedges. The smaller, shrub-like cultivars are also well-suited for container gardens and foundation plantings.
Urban Landscaping
Crape myrtles are particularly well-suited for urban environments, as they are relatively low-maintenance, drought-tolerant, and adaptable to a range of soil conditions. Their moderate size and open growth habit make them an ideal choice for planting along streets, in parks, and in other public spaces. The trees’ long flowering season and diverse color options also contribute to their popularity in urban landscapes.
Garden Design
The crape myrtle’s versatility extends to garden design, where it can be used as a focal point, accent plant, or backdrop for other ornamental species. Its multi-season interest, from the spring blooms to the fall foliage, makes it a valuable addition to both formal and informal garden settings. Gardeners often incorporate crape myrtles into mixed borders, foundation plantings, and even as part of xeriscaping efforts.
Crape Myrtle Cultural Significance
Historical Uses
Crape myrtles have a long history of use in their native Asian regions, where the wood has been used for furniture, musical instruments, and even traditional medicines. The flowers have also been used in religious and cultural ceremonies, reflecting the tree’s symbolic importance in these cultures.
