Description

Crapemyrtle (Lagerstroemia) is a beautiful summer flowering shrub that dies down to the ground as a perennial each year in Zone 6 Kansas. Flower colors include bright red, pink, magenta, purple, and white. Many cultivars have been released improving foliage color, disease resistance, and flower blooming length. Newer cultivars now have maroon or reddish foliage adding interest before blooming. Beautiful fall color is often overlooked; shades of red, orange, and purple develop when Night temperatures reach into the 40s. In Kansas, crape myrtles grow best with hot south or west exposures or on south facing berms or hillsides. But they are suitable in any garden location as long as they are in full sun, they will build enough energy to come back from complete winter top-kill each year. Generally are 40 inches of rain per year is sufficient without extra watering, but if drought conditions occur, flowering will be reduced or shortened. Brief periods of excessive water and saturated soils are tolerated adding to their versatility. Many people from the south associate Crapemyrtles as a tree. That is true that in Texas and much of the Southeast, beautiful tree forms with exfoliating bark will occur because of mild winters. In Oklahoma and Arkansas for example crapemyrtles are usually grown as large shrubs experiencing major winterkill every 5-10 years. In Kansas and Missouri, or where temperatures regularly get to 0°, all top growth will die back and they will be grown as a woody perennial. After flowering and beautiful fall color is dropped, many people leave crapemyrtles throughout the winter to enjoy the winter interest of the dried seed heads. By March or April, cut plants close to the ground and watch for new growth. Flowering occurs on new wood and is much larger and more dramatic on sprouts from the ground. Flowers are often twice as big when grown this way. In the past, only fast-growing tree size cultivars for appropriate and Kansas because they have the ability to recover the fastest from complete winterkill and grow into a flowering-sized shrub by July. Now there are dwarf cultivars that are wood-hardy to -10 zone 6 for those not wanting to worry about winterkill. No disease or pest problems. Crapemyrtle are awesome for pollinators in the late season garden and especially effective when combined with vitex, butterfly bush, and/or caryopteris. Lagerstroemia indica 'Rhapsody in Pink' was developed by Dr. Carl Whitcomb. This upright growing shrub features light pink summer flowers appearing against handsome foliage, which emerges a purple hue that persists most of the season.
