Crape Myrtle

Lagerstroemia indica

Crape myrtle is a multi-stemmed small tree that brings a tall, broad presence to a sunny plan. At about 25 feet tall and 20 feet wide, it works best as a focal tree with room for its canopy and visible branching. Summer into early-fall bloom gives it strong warm-season occupancy, while exfoliating bark keeps trunks visually useful after the flowers fade.

Placement and use

Place crape myrtle where its canopy can rise above lower planting layers without narrowing a walk, covering a patio, or crowding a roofline. Its multi-stemmed form suits an open lawn panel, a large island bed, or the back of a deep border where there is clear sightline space around the trunks. Keep a reachable edge beside the planting area for pruning and cleanup rather than packing the base tightly with woody shrubs.

Spacing and mature footprint

Set individual crape myrtles 15 feet apart, center to center. That planting distance is closer than the eventual 20-foot spread, so use it only where a lightly overlapping canopy or grouped effect is intended. For a single tree, reserve a roughly 20-foot-wide canopy zone and keep paths, walls, overhead structures, and permanent seating outside that mature footprint.

Three plants set 15 ft apart, center to center; shaded circles show the 20 ft mature spread.

Sun, water, and soil

Give this tree full sun, with at least six hours of direct light, so its crown does not become a shaded layer over nearby sun-loving beds. Use a well-drained planting area. It can tolerate dry conditions once established, fitting locations that are not intended for frequent irrigation; provide enough open soil around the root zone to avoid competition from dense permanent planting.[1]

Seasonal notes

Crape myrtle is deciduous, so plan for a more open canopy outside the growing season. Flowers occupy the tree from summer into early fall, making it especially useful behind later-season perennials or beside outdoor spaces used in warm weather. In leafless months, exposed branching and peeling bark remain part of the composition rather than a solid screen.[1][2]

Planning caveats

Use it within USDA Zones 6 through 9, but give Zone 6 placements extra protection from cold wind and avoid relying on top growth as a year-round screen. Winter injury can reduce above-ground growth in colder or exposed sites. Choose a position that still functions well if the tree is cut back or takes time to rebuild its canopy after a hard winter.[1][2]
