Crape Myrtle 'Autaugaville Purple'
Lagerstroemia 'Autaugaville purple'
In USDA zones 7b–8a around Raleigh, Durham, and Cary, Crape Myrtle 'Autaugaville Purple' is a tree used in Triangle yards when mature size, sun, and drainage fit the bed. Piedmont clay rewards a wide planting hole, a slightly high crown, and steady first-season water. Give it the open sky it wants; west-facing walls in July still cook tender foliage. Once rooted, it copes with summer dry spells better than thirstier ornamentals. Seasonal flowers are usually why it earns a street-facing spot. Fall planting is the usual window here; water through the first summer no matter the calendar.

Watering Procedure
Water consistently during the first season until roots are established. Once settled, this variety is notably resilient during our typical North Carolina dry spells.
Planting & Soil
Thrives in well-drained soil. Dig your hole twice as wide as the root ball but no deeper. Mix 30% compost with your native clay backfill to open up the soil—this helps the roots breathe and prevents water from pooling. Planting 'slightly high' also ensures the roots stay healthy.
Fertilization
Fertilize sparingly if at all. A light spring application is usually enough; over-fertilizing evergreens in our humidity can lead to weak, leggy growth.
Pruning / upkeep
Prune shortly after the flowers fade. This ensures you aren't cutting off the buds for next year's bloom cycle.
Common questions
Is Crape Myrtle 'Autaugaville Purple' a good plant for Raleigh and the Triangle?
Yes—when the site matches its light and drainage needs. Crape Myrtle 'Autaugaville Purple' is used in Raleigh, Durham, and Cary landscapes in USDA zones 7b–8a. Confirm mature width, overhead wires, and how wet the Piedmont clay stays after storms before you plant.
When should I plant Crape Myrtle 'Autaugaville Purple' in North Carolina?
Fall (October–November) is the safest window for Crape Myrtle 'Autaugaville Purple' in the Piedmont: soil is still warm, air is cooler, and roots can grow before summer. Spring after the last frost works if you can water deeply through the first hot season.
Will Crape Myrtle 'Autaugaville Purple' grow in Piedmont clay?
It can, with careful planting: wide hole, crown slightly above grade, and no water sitting on the root flare. Heavy, poorly drained clay is the usual failure mode—not summer heat alone.
Does Crape Myrtle 'Autaugaville Purple' lose its leaves in winter?
No. Crape Myrtle 'Autaugaville Purple' is evergreen and keeps foliage year-round, which is why it is used for winter structure and screening in Triangle yards.
How much sun does Crape Myrtle 'Autaugaville Purple' need?
It performs best in full sun—about 6 or more hours of direct light. Afternoon shade can help in reflected-heat courtyards, but too little sun usually means weaker flowering or open growth.
Is Crape Myrtle 'Autaugaville Purple' drought tolerant?
Once the root system is established in our clay, it handles dry spells better than average. It still needs consistent water the first season in the ground—drought-tough is not the same as plant-and-ignore.
