Hello,

Thank you for reaching out to MSU’s Ask Extension. Crape Myrtle trees are native to East Asia and can be found in USDA zones 7-9. They need full sun and thrive in hot, humid climates. They typically grow in the Southeastern United States, so they tend to struggle in Detroit’s metro-area (zone 6a-6b) due to our unpredictable cold winters. They can also suffer from severe die back, slow spring recovery, and a lack of blooms. Other key issues include winter damage, susceptibility to powdery mildew in humid, cloudy summers, and insect problems such as aphids/bark scale. A few cold hardy hybrid cultivars such as ‘Natchez” (white), ‘Sioux’ (soft pink) and ‘Tonto’ (red) do exist for zone 6 but can experience issues already mentioned. With any variety of Crape Myrtle, it is highly recommended they are planted in a south-facing location near a building or wall for warmth and 6-8 full hours of sun. Native Michigan trees such as Eastern Redbud, Flowering Dogwood, and Downy Serviceberry are all very similar in size, shape, trunk structure and flower color/longevity. These native trees are recommended because they will create resilient landscapes that can endure Michigan’s unpredictable cold winters. They foster local biodiversity, support wildlife and require minimal long-term maintenance.

Thank you for your question!
