Phoenix's Favorite Summer Flowering Shade Tree — Crape Myrtle Tree Crape Myrtle Tree (Lagerstroemia indica) is Phoenix's most popular summer-blooming shade tree — and for good reas on. This fast-growing deciduous tree explodes with massive clusters of blooms in pink, red, purple, or white from June through September, delivering color when nearly every other tree goes quiet in the desert heat. Easy to grow, drought-tough once established, and strikingly beautiful all season long. Whether you're shading a patio in Scottsdale, adding a bold focal point in Chandler, or creating a colorful streetscape in Mesa — Crape Myrtle Tree delivers all summer, every summer.

Its upright canopy reaches 15–25 feet tall while staying relatively narrow (6–15 feet wide), making it ideal for planting near patios, seating areas, and walkways where space is limited. Plant one or two flanking a patio entrance in Scottsdale or Peoria for a resort-quality look that blooms from early summer through fall. Pair with lower-growing Desert Spoon or Texas Sage for a layered, low-maintenance border. Street Trees and Privacy Screens Crape Myrtle's upright growth habit makes it one of the best street trees and driveway-lining trees in the Phoenix Valley. Space them 10–15 feet apart for an aligned boulevard effect, or 6–8 feet apart for a dense flowering privacy screen along a fence line. At maturity, a row of Crape Myrtles along a 30-foot fence requires about 3–4 trees; along a 60-foot run, 5–7 trees creates a full canopy screen. Their narrow profile won't interfere with overhead utilities when planted thoughtfully. 30 ft fence — 3–4 trees at 10 ft spacing 60 ft fence — 5–7 trees at 10–12 ft spacing Pool-Friendly Landscaping Crape Myrtle is one of the few flowering shade trees that works beautifully near Phoenix pools. Its root system is non-invasive, and it produces minimal litter outside of brief bloom drop periods. Plant 10–15 feet from the pool edge so the canopy provides afternoon shade without dropping excessive debris into the water. In Gilbert and Tempe, it's become a staple of resort-style backyard designs for exactly this reason. Desert-Modern Specimen Tree A single mature Crape Myrtle Tree is a showpiece on its own. Its multi-stemmed silhouette, peeling cinnamon bark, and brilliant summer blooms make it one of the most ornamentally valuable trees in the entire Phoenix landscape palette. Plant as a solo specimen in a gravel bed or raised planter for dramatic effect. The fall foliage adds a bonus season of orange and red color before leaves drop — a rare treat in the desert Southwest. Best Time to Plant Crape Myrtle Tree in Phoenix Fall (October–November) is the ideal planting window. Warm soil encourages root establishment while cooler air temperatures reduce transplant stress. A fall-planted Crape Myrtle gets 6–8 months of root growth before facing its first Phoenix summer, dramatically improving performance and long-term health. Spring (February–April) is the second-best option. Avoid summer planting when possible — the heat demands intensive daily watering that stresses newly transplanted trees. How to Plant Crape Myrtle Tree Dig wide, not deep — Excavate 2–3x the root ball width, matching the container depth exactly. Check for caliche — Break through any hardpan layer so water can drain freely below the root zone. Backfill with native soil — A 20% organic amendment blend is acceptable; avoid heavy clay mixes. Spacing — 10–15 feet apart for street trees or screens; 15–20 feet from structures as a specimen. Water basin — Build a 3–4 inch earthen berm around the drip line to hold irrigation water at the root zone. Mulch — Apply 2–3 inches of bark or decomposed granite mulch to retain moisture and reduce soil temperature. Watering Crape Myrtle Tree in Phoenix First Year Watering Schedule Weeks 1–2: Water every 1–2 days, deep and slow (20–30 minutes). Months 1–2: Every 3–4 days. Months 3–6: Every 7–10 days (every 5–7 days during peak summer heat). After Year 1: Every 10–14 days in summer; every 3–4 weeks in winter. Established Crape Myrtles are remarkably drought-tolerant and rarely need supplemental winter water. Drip Irrigation Use a 2–4 GPH emitter placed 18–24 inches from the trunk during establishment. As the tree matures, move emitters outward to the drip line. Established Crape Myrtles can thrive on Phoenix's natural winter rainfall with no supplemental irrigation. In summer, one deep weekly watering at the drip line is sufficient for trees over two years old. How fast does Crape Myrtle Tree grow in Phoenix?Crape Myrtle is one of Phoenix's fastest-growing ornamental trees — typically adding 3–5 feet per year in Phoenix's hot climate. A 10/15-gallon nursery tree can reach full canopy height of 15–20 feet within 3–4 years of planting. When does Crape Myrtle bloom in Phoenix?In Phoenix, Crape Myrtle typically begins blooming in June and continues through September — a full 3–4 month bloom window. The exact start depends on the year's heat accumulation. Established trees in full sun often bloom earlier and more profusely than shaded or newly planted specimens. What colors does Crape Myrtle Tree come in?This listing is for the general Crape Myrtle Tree in assorted colors including pink, red, purple, and white. If you want a specific color, Three Timbers also carries dedicated color varieties including Dynamite Red Crape Myrtle Tree, Purple Crape Myrtle Tree, and White Crape Myrtle Tree. Is Crape Myrtle drought tolerant once established?Yes — established Crape Myrtle Trees are very drought-tolerant. After the first year of establishment watering, a mature Crape Myrtle can survive Phoenix summers on minimal supplemental irrigation. This makes it one of the most water-efficient flowering shade trees available for Arizona landscapes. Can I plant Crape Myrtle near my pool?Yes — Crape Myrtle is one of the best flowering trees for pool-side planting in Phoenix. Its root system is non-invasive, and bloom drop is brief and manageable. Plant 10–15 feet from the pool edge and you'll get beautiful summer color and afternoon shade without excessive pool maintenance. You May Also Like Dynamite Red Crape Myrtle Tree — The most vivid red-blooming Crape Myrtle available, producing brilliant true-red flowers from May through October in Phoenix landscapes.

How Many Crape Myrtle Tree Do I Need? Crape Myrtle stays narrow (6 to 15 feet wide) and upright, so it works as a single specimen, a spaced street line, or a tight flowering screen. Use this guide to estimate counts: Goal Spacing Trees needed Single patio specimen n/a 1 Matched pair flanking an entry 10 to 12 ft apart 2 Street or boulevard line, 30 ft 10 ft on center 3 to 4 Dense flowering privacy screen, 60 ft 6 to 8 ft on center 8 to 10 Space 10 to 15 feet apart for an open boulevard look, or tighten to 6 to 8 feet when you want the row to close into a solid summer screen. Crape Myrtle Tree Season-by-Season in Phoenix Spring (Feb–Apr): Leafs out and builds the framework for summer bloom. Strong second planting window. New growth draws bees as buds form. Summer (May–Sep): The headline season. Massive bloom clusters in pink, red, purple, or white right through triple-digit heat and reflected heat off walls and pavement, often flushing harder after monsoon rain (Jul–Sep). Few trees give this much color in peak Phoenix summer. Fall (Oct–Nov): Bloom tapers as foliage turns orange and red, a rare fall display for the low desert. Best planting season here. The peeling cinnamon bark stands out as leaves drop. Winter (Dec–Jan): Bare and dormant, showing off its sculptural multi-stem trunks and cinnamon bark. Very cold-hardy (rated to roughly 5°F), so Valley frost is a non-issue.

Desert Willow: an Arizona native with trumpet blooms that overlaps the crape myrtle's long summer show. Is Crape Myrtle Tree Right for Your Yard? Crape Myrtle thrives in full sun and reflected heat, in well-drained alkaline or caliche soil, and its narrow upright form fits tight patios, pool surrounds, and street lines where a wide canopy won't work. It is drought-tolerant after year one, frost-hardy here, non-invasive at the root, and one of the few trees giving four months of summer color. Not a fit if: you need dense year-round shade or an evergreen screen, since it is deciduous and casts only light, filtered shade through a narrow crown. Plant in full sun for the best bloom, and skip the harsh "topping" cut, which ruins the natural form. Show more
