Are crape myrtles monoeicious or dioecious?

Crape myrtles (Lagerstroemia spp.) are generally considered to be monoecious, meaning that a single plant has both male and female flowers. This allows them to produce seeds through self-pollination or cross-pollination with other nearby crape myrtles. While most varieties are monoecious, some cultivars may exhibit variations in flower structure and reproductive traits.
