Crape Myrtles Alluvial Terrace Nursery sources only mildew resistant cultivars that may not be available from other nurseries. We typically grow "Multi Stem" plants and prune to show off their mottled bark and complex branch structures. Our favorites are Lagerstroemia fauriei "Fantasy" and Lagerstroemia indica "Tonto". Please check the plant list  for our complete listing.   Our nursery finds this link very helpful www.usna.usda.gov/Research/Herbarium/Lagerstroemia/index.html
