Lagerstroemia x fauriei 'Pecos' xera plants

Lagerstroemia x fauriei ‘Pecos’

A deservedly popular tree in western Oregon for several reasons. Large globose panicles of clear pink flowers begin in urban areas as early as the beginning of July and repeat bloom until September. The open and vase shaped habit is graceful and bends gently under the weight of the huge flower trusses. In time this 15′ tree develops some of the best exfoliating bark of the genus. In late summer on trees older than 3 years the top layer of bark sloughs off revealing smooth, rich, chocolate brown trunks. Amazeballs. The bark is showy throughout winter. In autumn the foliage turns to shades of maroon and red. This crape myrtle MUST HAVE regular irrigation to grow and bloom. Excellent small garden tree with some of the lowest heat requirements to bloom. Water. You must water. National Arboretum release 1987, Spectacular tree in western Oregon.
