Crape Myrtle (Lagerstroemia indica)

Long-blooming ornamental tree with vibrant summer flowers and bark

The Crape Myrtle stands as one of the most distinctive ornamental trees in modern landscapes, earning its nickname "the lilac of the South" for good reason. This striking tree typically grows 15-25 feet tall, though some varieties can reach heights of 40 feet. Its most notable features are its abundant clusters of crinkled, crepe-paper-like flowers that bloom in vibrant shades of pink, red, purple, or white. The tree's smooth, multicolored bark peels away in puzzle-like patterns throughout the year, revealing a mottled trunk that provides visual interest even in winter months when the tree is dormant.

Native to Southeast Asia, particularly southern China and Korea, Crape Myrtles were first introduced to Charleston, South Carolina in 1786 by French botanist André Michaux. The tree's name combines "crape" (referring to the crinkled, crepe-like texture of its flowers) and "myrtle" (due to its resemblance to true myrtle leaves). It quickly became a staple in Southern gardens, earning its place as an iconic symbol of Southern landscapes, and has been extensively hybridized to create hundreds of varieties suited to different climates and preferences.

Crape Myrtles thrive in full sun, requiring at least six hours of direct sunlight daily to produce their spectacular blooms. These sun-loving trees perform best in USDA hardiness zones 6-10, though they're particularly well-suited to zones 7-9. The blooming season typically begins in early summer and can extend into fall, with peak flowering occurring during the hottest months of summer. They prefer well-draining soil and, once established, display remarkable drought tolerance, making them excellent choices for water-conscious landscaping.

When caring for Crape Myrtles, several important considerations should be noted. First, resist the urge to perform "crape murder" – the unfortunate practice of severely topping the trees, which can lead to weak branch structure and reduced blooming. Instead, focus on selective pruning in late winter to maintain shape and remove crossing branches. Additionally, powdery mildew can be an issue in humid conditions with poor air circulation, though many modern cultivars have been bred for resistance to this fungal disease. While generally pest-resistant, they can occasionally be troubled by aphids, which typically don't require treatment as they rarely cause significant damage.

The versatility of Crape Myrtles extends beyond their ornamental value. Their dense canopy provides excellent summer shade, while their modest root system makes them suitable for urban environments and planting near structures. The trees are notably long-lived, with some specimens known to survive over a century, and they continue to provide multi-season interest throughout their lives. In autumn, the foliage transforms into striking shades of yellow, orange, and red before falling to reveal the artistically mottled bark beneath, ensuring year-round landscape appeal.
