Phoenix’s Most Colorful Summer-Blooming ShrubCrape Myrtle Bush (Lagerstroemia) is the ultimate summer color machine for Phoenix Valley landscapes. These heat-loving shrubs explode with vibrant blooms in pink, red, purple, or white from June through October — the exact months when most other plants struggle in the desert heat. Growing 6–10 feet tall and wide, Crape Myrtles deliver stunning flower displays, attractive peeling bark, and brilliant fall foliage color. Whether you’re screening a Scottsdale pool area, lining a driveway in Gilbert, or creating a colorful border in Chandler — Crape Myrtle Bush is the proven performer.Crape Myrtle Bush Plant Details Attribute Detail Scientific Name Lagerstroemia indica Common Names Crape Myrtle, Crepe Myrtle, Crapemyrtle Mature Height 6–10 feet Mature Width 6–10 feet Growth Rate Fast — 2–3 feet per year in Phoenix Sun Full sun (6+ hrs).

Plant 4–6 feet apart for a flowering hedge that fills in within 2–3 years. The summer bloom season adds a wall of color that no other screening plant can match in Phoenix heat.Pool-Friendly LandscapingCrape Myrtles are a top choice for pool areas — their non-invasive root system won’t damage hardscape, and the showy blooms create a resort-like atmosphere. The deciduous habit means less debris during winter pool maintenance. Plant 6–8 feet from the pool edge for best results.Foundation Plantings & Accent ColorUse Crape Myrtles as colorful foundation shrubs alongside homes, or as specimen plants in island beds and courtyard gardens. Their peeling cinnamon-colored bark provides winter interest even after leaves drop. Pair with evergreen plants like Texas Sage or Indian Hawthorn for year-round structure.Best Time to Plant Crape Myrtle Bush in PhoenixFall (October–November) is ideal — warm soil promotes fast root establishment while cooler air reduces transplant stress. Your plant gets 6–8 months of root growth before its first Phoenix summer bloom season. Spring (February–April) is the second-best window. Avoid summer planting when possible.How to Plant Crape Myrtle Bush Dig wide, not deep — 2–3x the root ball width, same depth Check for caliche — break through any hardpan layer for drainage Backfill with native soil — a light 20% compost blend encourages blooming Spacing — 4–6 feet apart for hedges; 8–10 feet for individual specimens Water basin — build a 3–4 inch ring to direct water to roots Mulch — 2–3 inches of bark or gravel mulch to retain moisture Watering Crape Myrtle Bush in PhoenixFirst Year Watering Schedule Weeks 1–2: Every 1–2 days, deep and slow (20–30 min) Month 1–2: Every 3–4 days Month 3–6: Every 5–7 days (every 3–5 days in peak summer) After Year 1: Every 7–10 days summer; every 2–3 weeks winter Drip IrrigationPlace two 2-GPH emitters 18–24 inches from the trunk on opposite sides. Crape Myrtles need slightly more water than most desert plants but are still remarkably heat-tolerant once established.How fast do Crape Myrtles grow in Phoenix?Very fast — expect 2–3 feet of growth per year. Most plants reach blooming size within the first year after planting and full mature size in 3–5 years.Do Crape Myrtles lose their leaves in winter?Yes, they are deciduous and drop their leaves in late fall. Before dropping, the foliage often turns beautiful shades of orange, red, and yellow. The attractive peeling bark provides winter interest.What color blooms will my Crape Myrtle have?Bloom color depends on the cultivar. Three Timbers carries varieties in pink, red, purple, and white. Ask our team about specific color availability when ordering.Do Crape Myrtles need pruning?Light pruning in late winter (January–February) encourages more blooms. Remove spent flower clusters during the season to promote reblooming. Avoid heavy “crape murder” topping — it damages the plant’s natural form.You May Also Like Texas Sage — Evergreen purple-blooming shrub that complements Crape Myrtles perfectly Bottlebrush Bush — Red bottle-shaped blooms and evergreen foliage for year-round color Bay Breeze Indian Hawthorn — Compact evergreen shrub with pink spring flowers Butterfly Bush — Another pollinator magnet with long, colorful flower spikes How Many Crape Myrtle Bush Do I Need?

Crape Myrtle Bush Season-by-Season in Phoenix Spring (Feb–Apr): Leafs out from bare winter stems; vigorous new growth sets up the summer bloom. Good second planting window. Summer (May–Sep): The main event: thrives in extreme heat and blooms heavily June through October when most plants stall. Needs slightly more water than true desert shrubs, especially during the hottest stretch. Fall (Oct–Nov): Bloom finishes, then foliage turns orange, red, and yellow before dropping. Prime planting season in the Valley. Winter (Dec–Jan): Deciduous and dormant, showing off cinnamon, peeling bark. Very cold-hardy (to roughly 5°F), so Phoenix winters pose no risk; late-winter is the time for light shaping pruning. At a Glance ✔ Pollinator-Friendly ✔ Heat-Loving (Reflected-Heat Tolerant) ✔ Pool-Friendly (Low-Litter) ✔ Low-Maintenance ✔ Cold-Hardy to 5°F Plant It With Texas Sage: an evergreen purple bloomer that adds winter structure under deciduous crape myrtle. Bottlebrush Bush: red brushes and evergreen foliage for year-round color alongside. Bay Breeze Indian Hawthorn: a compact evergreen front-of-border partner with pink spring flowers.

Crape Myrtle Bush thrives in full sun and intense summer heat, in well-draining soil (it adapts to caliche if drainage is opened up), with low-to-moderate water once established. It is ideal for summer-color screens, pool surrounds, and driveway plantings where you want bold bloom when it is hottest. Not a fit if you need year-round evergreen screening or a truly no-water plant: it drops its leaves in winter and wants a bit more irrigation than native desert shrubs.
