Selected National Arboretum Crape Myrtle Introductions and Their Performance in Western Oregon:
Lagerstroemia x fauriei 'Acoma'
A small tree with a pendulous habit to fourteen feet tall. Bark is a glossy taupe. Flowers are pure white and abundant, appearing as early as the first part of August, in favorable locations and continuing to late September. Fall color is red to yellow. Readily available at most large nurseries, and resistant to powdery mildew.

Lagerstroemia x 'Arapaho'
A fast-growing, upright cultivar to twenty feet, with a pronounced vase shape. Released in 2003, this is the first triple hybrid crape myrtle to come from the National Arboretum's breeding program. Spectacular deep cranberry red floral trusses are borne from late August through September. Bark is rough and mottled tan, but not as showy as others. Fall color is deep maroon.
