The largest triple hybrid from the National Arboretum has yielded an excellent true red flowered, disease resistant and reliable Crape Myrtle. Fast growing to 20′ tall but just 8′ wide it forms a very upright tree. The huge true red flower trusses (to 8″ long) begin in urban areas in late July and continue unabated for two months. New growth is maroon and still retains hints of that as it changes to green- giving this tree a darker look. We have found that it is slightly tender when young- freezes back in cold winters but it rebounds quickly in summer and established trees see no damage. Rich to average (including heavy clay) soils with regular deep summer irrigation for earlier and more prolific bloom. Bark is fair becoming a mottled patchwork of tan. Fall color is brilliant red. Fast growing- easily 3′-4′ per year in well irrigated trees. Mildew resistant. Full, hot sun in a hot position.
