Lagerstroemia 'ACOMA'

Crepe myrtle is a flowering shrub or small tree from China. It was first introduced to the USA and the UK in the 18th century. The original plant lagerstroemia indica is too tender and not too pretty so breeders were working on further hybridization and the most attractive varieties available now are believed to be results of crossing with l.speciosa and l.fauriei. Far more important news for us is the fact that among those finished plants were selected others that survived lower temperatures than what was common in the areas of natural habitat so we have a few myrtles that can grow even in our climate. Some were selections, other further hybrids.

Acoma is a hardy crepe myrtle hybrid variety with white flowers. They are composed in smaller panicles compared to e.g. Natchez variety but offer a nice contrast with the background of leaves that turn light burgundy red just before the plant sets flowers. Blooming time is early August until mid to end September. Deciduous leaves are 3-4 cm long, elliptic to obovate, very glossy, olive green in spring, with some light burgundy red tones in summer, and turning carmine red and golden yellow in autumn.

Crepe myrtle needs little care. They need full sun with zero shade during the day. Pruning is important in colder zones and will secure flowering: cut back last year's growth to about a third of its original size. Do so in spring after danger of frosts. The plant will make strong news shoots that will bear flowers. Grow it in well-drained soil that should be kept moist before it gets fully established. If cultivated in acid soil the plant will make fabulous colour play of autumn foliage. Crape myrtle needs heavy mulching in winter and some mulch in summer to retain moisture. Fertilize in spring to encourage growth (nitrogen-based fertilizers), and in summer to encourage flowering (phosphorus-based fertilizers). It is top hardy to about -21°C and root hardy to about -25°C (USDA zone 6).
