Crape 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.
DYNAMITE® is possibly the reddest crepe myrtle variety known to trade. It produces large (30x20 cm), upright panicles of the richest red shade you may have seen. Flowering begins in late July or early August and continues till the last sunny and warm days of autumn.
The deciduous leaves are leathery, oval, crimson red when they emerge, and turning deep green soon after. In acid soil they gain fantastic fiery red and orange shades in autumn.
When they fall down older plants reveal flaking-off bark, similar to what plane trees or stewartias do, leaving a mosaic pattern on the smooth trunks.
DYNAMITE® was selected among 2,000 seedlings by Carl E.Whitcomb from Oklahoma, USA, and patented in 1996 under the name Whit II, patent No. PP10,296. The achievement was gained thanks to EMS (ethylmethane sulfonic acid methyl ester) which is a substance known for causing mutation when seeds are treated with it.
Crape myrtles need little care. They need full sun with zero shade during the day. Pruning will secure fresh growth and good flowering: cut back last year's growth to about a third of its original size. Do so in spring after danger of all 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. The soil should be very well-drained and fertile. It needs heavy mulching in winter and some mulch in summer to retain moisture. Overfertilizing will cause excessive growth but no flowers. Above ground wood is hardy to about -21°C (USDA zone 6b), and roots and near ground woody structure withstands -25°C.
