Scientific: Lagerstroemia indica
Common: Crape myrtle
Family: Lythraceae
Origin: India, southeast Asia

Hardiness zones:
Sunset Treated as perennial in 1-3, excellent in 7-10, 12-14 and 18-21
USDA 6 (freeze damage likely), 7-11

Landscape Use: Accent shrub, specimen small multiple trunk tree, entryway plantings, dwarf cultivars as container plants and landscape shrubs, mesic design themes in Phoenix only

Form & Character: Deciduous, smooth trunk, bright summer color, clean during summer but can look dead during winter despite wonderful trunk characteristics

Growth Habit: Depends on cultivar, ranging from dwarf to 3' to upright to 30'

Foliage/texture: Oblong elliptic to rounded, reddish when young maturing to green, 2" long, glabrous or pubescent on veins, medium texture

Flowers & fruits: Multiple, terminal panicles of small flowers to 1 1/2" across, colors ranging from white to pink to red to violet; fruit a brown capsule

Seasonal color: Flowers in summer

Temperature: Hardy, though not heat tolerant of western exposures or temperatures above 115oF. Avoid reflected light and heat. Best used in mesic surroundings with lots of landscape vegetative cover.

Light: Full sun in areas of good air circulation surrounded by green space.

Soil: Prefers clay loam, performs poorly in sandy soil

Watering: Regular

Pruning: Depends on use, prune in late winter

Propagation: Mostly cutting

Disease and pests: Aphids, scale, white flies, sooty mold, powdery mildew is especially problematic if air circulation is poor.

Additional comments: In Phoenix, crape myrtle usually suffers from mid to late summer heat stress that manisfests as a foliar marginal browning and/or premature leaf loss. Crape myrtle does perform wonderfully in the hot inland valleys of coastal California.

Always specify crape myrtle by cultivated variety that matches plant vigor to planting location. Some sturdier, upright and tree-like cultivars are hybrids between L. indica and L. faurei. Crape myrtle's winter deciduous habit is not preferred by many in lower desert climate areas where 'green' is expected during outdoor winter months.

There is also a series of cultivars in the 3-4 foot range known as the 'Petite' series that offer a wide variety of floral colors in a dwarf plant form of crepe myrtle, (e.g. 'Petite Plum'- deep purple). In addition, there are miniature cultivars of crepe myrtle known as the 'Dixie' series that are less than 3' tall. These mini-crepe myrtles tend to not be as cold hardy as those above, have a rather weeping growth habit, and do well as patio container plants for decorative display when alone or mixed with short colorful annual bedding plants, grow in partial shade, no western exposure. The 'Dixie' cultivars include 'Baton Rouge', and 'Bourbon Street' - both deep red, and 'New Orleans' - a purple flowering cultivar only 8-24 inches. The list provided above is only a small portion of the number of named cultivars of crepe Myrtle that are available.
