Arapaho Crape Myrtle is a deciduous tree or shrub, with an upright and spreading growth, which looks best if planted in groups, as a hedge or small, single tree. Single or multi-stemmed small upright tree will grow up to 6 m tall and 3 m wide in 10 years. Arapahos are one of the faster growing Crape Myrtles, shooting up to 90-150 cm per year.
‘Arapaho’ grows and flowers best in a heavy loam to clay but moist soil in a place in full sun but will also grow well in hot, difficult sites. Be sure to plant your Arapaho Crape Myrtle in full sun. If they get too much shade, the bright red color of the flowers may fade and the flowering will be reduced. Follow a regular watering schedule during the first growing season to establish a deep, extensive root system. Once established it will only need only occasional water.
It can be easily propagate by softwood, semi-hardwood, hardwood or root cuttings but the preferred methods are softwood and semi-hardwood cuttings taken before flowering.
