Crape Myrtle ‘Catawba’

Crape Myrtle 'Catawba'

Crape Myrtle ‘Catawba’ is a classic deciduous shrub or small tree admired for its vivid purple flowers and attractive, multi-season interest. Introduced by the U.S. National Arboretum, it has long been a favorite in Southern landscapes for its reliable performance and ornamental charm.

From midsummer to early fall, ‘Catawba’ produces large, crinkled flower clusters in a rich, true purple hue—uncommon among crape myrtles. These blooms appear in abundance atop the branches and contrast beautifully with its dark green foliage, which turns shades of red and orange in autumn.

The plant’s exfoliating bark adds winter interest, peeling to reveal a smooth, mottled surface in tones of gray and tan. Its graceful, upright habit makes it a perfect choice for use as a specimen tree, privacy screen, or colorful hedge.

Growing to about 10–15 feet tall and 8–12 feet wide, ‘Catawba’ is a more compact variety compared to some other crape myrtles, making it ideal for medium-sized landscapes. It thrives in full sun and is prized for its disease resistance, especially to powdery mildew.

Planting: Choose a location in full sun with well-drained soil. Plant with enough space (8–10 feet apart) to accommodate its mature spread and encourage good air circulation, which helps prevent disease.

Watering: Water regularly during the first year to establish roots. Once established, ‘Catawba’ is moderately drought-tolerant but performs best with consistent moisture during dry spells.

Pruning: Prune in late winter or early spring before new growth emerges. Remove any crossing branches or suckers at the base to maintain a clean structure. Avoid heavy topping, which ruins the natural form.

Pest & Disease Control: ‘Catawba’ is bred for resistance to powdery mildew, a common issue in older varieties. Check for aphids and treat with insecticidal soap if needed. Promote airflow and avoid overhead watering to discourage disease.

Soil Tips: Prefers well-drained, slightly acidic to neutral soil. Avoid soggy areas. Mulch annually to retain moisture and regulate soil temperature, but keep mulch a few inches away from the trunk.
