Crepe myrtles like full sun. While they will tolerate a few hours of shade per day, they need at least six hours of sunlight and are very heat-tolerant, perfect for our hot Southern climate. Without the sun they need, they may not have many or any blooms. A Muskogee can reach a height of 30 feet and a width of 15-20 feet with a massive trunk caliper. Muskogee flowers are light lavender and very prolific, with an unusually long blooming period lasting up to 120 days.
