The 'Zuni' Crape Myrtle (Lagerstroemia indica 'Zuni') brings clouds of unusually lovely lavender blossoms to the landscape from July to September. A vigorous plant, if left unpruned it can reach 11 feet in height and spread. If cut back to 8 inches in winter, it will grow to about 4 feet tall the next year. 'Zuni' is also known for excellent mildew resistance.
