Twilight Crape Myrtle

Twilight crape myrtle is a deciduous shrub or small tree with large summer flower clusters that open dark plum-purple and develop fuchsia-pink tips. Its purple-green leaves, autumn color, and peeling brown-gray bark bring interest beyond the bloom season. ## Size and placement The Royal Horticultural Society lists a mature height of 2.5–4 metres (about 8–13 feet) and a spread of 1.5–2.5 metres (about 5–8 feet). Allow room for this taller, bushy form rather than placing it in a narrow bed. Plant in full sun for the best flowering; the RHS notes that hot summers support bloom. This cultivar is commonly listed as Lagerstroemia indica ‘Twilight’. ## Growing conditions Use moderately fertile, well-drained soil. The RHS lists chalk, loam, and sand as suitable soil types and recommends acid to neutral conditions. The profile also suggests sheltered, south- or west-facing positions in its UK context; local winter conditions will affect performance elsewhere. A mature shrub can tolerate occasional dry soil, but moisture during dry spells supports flowering. ## Maintenance Water thoroughly at planting, then weekly when rainfall is absent during the first two months. Established crape myrtles tolerate drought, though watering during a dry flowering season can improve bloom. The RHS places this cultivar in pruning group 1: remove diseased, damaged, congested, or crossing shoots, and leave healthy growth largely undisturbed.
