Optimal Hardiness Zones for Crape Myrtle 'Catawba': 7a-9b

Crape Myrtle 'Catawba' Temperature Tolerance

❄️ Cold Tolerance Specifics

Crape Myrtle 'Catawba' is remarkably resilient, surviving temperatures as low as 0°F (-18°C). This cold tolerance allows it to endure winter conditions, but frost can still impact its growth and flowering.

Frost can delay blooming and reduce the overall vigor of the plant. Understanding this can help gardeners plan for potential setbacks in colder months.

☀️ Heat Tolerance Specifics

On the flip side, Crape Myrtle 'Catawba' thrives in warmer climates, particularly in hardiness zones 7a to 9b. Optimal growth occurs when temperatures are consistently warm, promoting lush foliage and vibrant blooms.
