White-flowering crape myrtles rank among the most versatile landscape trees in warm and temperate climates, and a handful of cultivars have proven themselves over decades of use. ‘Natchez,’ a large hybrid developed by the U.S. National Arboretum, is widely considered the benchmark for white crape myrtles thanks to its vigorous growth, cinnamon-toned peeling bark, and strong resistance to powdery mildew. But ‘Natchez’ is far from the only option, and the best choice depends on the space you have, the climate you garden in, and what you want the tree to do in your yard.
Large White Crape Myrtles for Shade and Street Presence
If you have room for a tree that will reach 20 to 30 feet tall, the large white cultivars deliver the most dramatic summer bloom. ‘Natchez’ is the one you will see recommended most often, and for good reason. It is a hybrid of Lagerstroemia indica and Lagerstroemia fauriei, the Japanese species whose genes contribute both powdery mildew resistance and that striking, smooth bark that peels in patches of tan, cinnamon, and gray. A mature ‘Natchez’ in full bloom is genuinely eye-catching, with dense clusters of pure white flowers from early summer well into fall. It grows quickly, tolerates heat and moderate drought once established, and develops a broad, vase-shaped canopy that works well as a lawn specimen or along a street.
‘Townhouse’ is another large white cultivar from the National Arboretum breeding program. It has a narrower, more upright growth habit than ‘Natchez,’ which makes it a practical pick for tighter spaces where you still want height. It also inherits the mildew resistance that came from the L. fauriei parentage. ‘Sarah’s Favorite,’ sometimes sold as ‘Sarah’s Favourite,’ is a third large white option with a somewhat open, upright form and good bark interest. It is widely planted across the southeastern United States and holds up well in the heat.
All three of these large cultivars are best suited for USDA hardiness zones 7 through 9, though some gardeners in sheltered spots in zone 6 push their luck successfully. In those marginal zones, expect occasional dieback after a harsh winter, with regrowth from the base the following spring.
Medium and Dwarf Whites for Smaller Spaces
Not every landscape has room for a 25-foot tree, and breeders have produced white crape myrtles at nearly every size. ‘Acoma,’ another National Arboretum release, is one of the most popular medium-sized options. It tops out around 10 to 12 feet with a graceful, semi-weeping habit that sets it apart from the more upright cultivars. The pendulous branches create a layered look that reads as almost Japanese in style, and the white flower clusters are produced generously. Like ‘Natchez,’ ‘Acoma’ carries powdery mildew resistance from its L. fauriei heritage.
For even smaller spaces, foundation plantings, or container use, several dwarf and semi-dwarf whites exist. ‘Glendora White’ and ‘Byers Wonderful White’ are older selections of L. indica that stay compact, though they lack the mildew resistance bred into the hybrids. Some of the newer compact series, like the Enduring Summer and Early Bird lines, include white options bred for earlier bloom and tidier habit. These typically stay under six feet and suit borders, mass plantings, or spots where a full-sized tree would overwhelm the design.
When choosing among sizes, think about the mature canopy width as much as the height. A crape myrtle planted too close to a building or walkway will need constant pruning, and aggressive pruning — sometimes called “crape murder” — leads to weak, knobby regrowth that ruins the tree’s natural form and can reduce flowering. Give the plant the space its mature size needs, and you will spend far less time with the loppers.
Why Disease Resistance Matters When Choosing a Cultivar
Powdery mildew has been the single biggest headache for crape myrtle growers for generations. The fungus coats leaves and flower buds in a whitish-gray film, stunts growth, and makes an otherwise beautiful tree look sickly. The breakthrough came when breeders at the U.S. National Arboretum crossed the common L. indica with L. fauriei, a species that carries strong natural resistance to the disease. That program has released over 650 new cultivars of woody ornamental plants over its history, with disease-resistant crape myrtles being one of its signature contributions.1ISHS Acta Horticulturae. Good genes – using germplasm and breeding to create new plants at the U.S. National Arboretum
For white-flowering varieties specifically, ‘Natchez,’ ‘Acoma,’ and ‘Townhouse’ all trace back to that hybrid program and carry meaningful mildew resistance. Older pure L. indica whites like ‘Glendora White’ do not, so if you live in a humid climate where mildew pressure is high, they may need fungicide applications or they will look shabby by midsummer. In drier climates — parts of Texas, the Southwest, inland California — mildew is less of a problem and those older cultivars can do fine without intervention.
When shopping, the presence of a Native American tribal name (Natchez, Acoma, Tonto, Muskogee, and so on) is a useful shorthand. The National Arboretum used tribal names for its hybrid releases, and they all carry at least moderate mildew resistance. Not every white crape myrtle on the market follows that naming convention, though, so checking the specific cultivar’s parentage or disease ratings before buying is still worthwhile.
Crape Myrtle Bark Scale and What It Means for Your Choice
A newer pest concern is crape myrtle bark scale, an invasive insect first detected in the United States around 2004 that has since spread across much of the Southeast and into parts of the Mid-Atlantic and Midwest. The scale insects feed on bark, producing a black sooty mold that discolors the trunk and branches. Unfortunately, no crape myrtle cultivar tested so far has shown true resistance to the pest. In a trial comparing host suitability across six species of Lagerstroemia, only L. speciosa — a tropical species rarely grown in American landscapes — was significantly less infested.2Oxford Academic. Ecology, impact, and management strategies for the invasive crapemyrtle bark scale (Hemiptera: Eriococcidae)
That means your choice of white cultivar does not meaningfully change your bark scale risk. Whether you plant ‘Natchez’ or ‘Acoma’ or a dwarf selection, the pest may eventually find it if you are in an area where bark scale is established. Management relies on cultural practices like encouraging beneficial insects, applying horticultural oil in the dormant season, and, when infestations are severe, systemic insecticides. Keeping trees healthy through proper watering, mulching, and avoiding unnecessary pruning stress all help the plant tolerate some level of scale feeding without serious decline.
Cold Hardiness and Pruning Timing
White crape myrtles share the same general cold-tolerance range as other crape myrtle colors: most hybrid cultivars are reliably hardy through zone 7, with many surviving in zone 6 if planted in a sheltered, south-facing location. But how you manage the plant in fall can shift that tolerance by a meaningful margin. Research on ‘Natchez’ specifically found that pruning before January reduced the tree’s cold hardiness by about 3°C compared to unpruned controls. The effect held across two consecutive years of testing.3HortScience. FALL PRUNING EFFECTS COLD HARDINESS OF FIELD-GROWN CRAPE MYRTLE
Three degrees Celsius may not sound like a lot, but in a zone 7 winter where temperatures occasionally dip into the single digits Fahrenheit, that gap can be the difference between a tree that sails through winter and one that dies back to the ground. The practical takeaway is simple: if you need to prune your white crape myrtle, wait until January or later. In zones 8 and 9, where hard freezes are rare, the timing matters less, but it is still a good habit to let the tree go fully dormant before you cut.
When dieback does happen, most crape myrtles will resprout vigorously from the roots in spring. You may lose that season’s bloom or get reduced flowering since buds form on new growth, but the plant itself usually recovers. In the coldest parts of the range, some gardeners treat crape myrtles as die-back shrubs rather than trees, cutting them to the ground each spring and letting the new growth flower by midsummer.
White Flowers and Pollinator Value
Crape myrtles bloom during mid to late summer, a window when many other flowering trees and shrubs have already finished. That timing makes them genuinely useful for pollinators. Research in Florida found that crape myrtles serve as a pollen source for several native bee species as well as honey bees, and that planting a mix of cultivars can support a broader diversity of pollinator groups across the season.4Florida Entomologist. Use of Crape Myrtle, Lagerstroemia (Myrtales: Lythraceae), Cultivars as a Pollen Source by Native and Non-Native Bees (Hymenoptera: Apidae) in Quincy, Florida
If you are choosing a crape myrtle partly for pollinator support, flower color matters more than you might expect. A study evaluating bee visitation across nine color categories of crape myrtle found that dark pink, dark purple, and white were the flower colors most frequently visited.5Environmental Entomology. Differential Bee Attraction Among Crape Myrtle Cultivars (Lagerstroemia spp.: Myrtales: Lythraceae) So a white crape myrtle is not a compromise on pollinator appeal — it is actually one of the more attractive options for bees. Combined with the fact that crape myrtles fill a summer pollen gap when many other sources are scarce, a well-placed white cultivar pulls double duty as both an ornamental feature and a functional part of your garden’s ecology.
Design Considerations for White-Flowering Varieties
White flowers are more versatile in a landscape design than strongly colored ones. A hot pink or magenta crape myrtle makes a bold statement but can clash with certain house colors, perennial beds, or neighboring plantings. White goes with everything, which is part of why ‘Natchez’ is so widely planted in commercial and residential landscapes alike. It reads as elegant without competing with other elements in the yard.
That said, white crape myrtle flowers can show damage more visibly than darker colors. Spent blooms turn brown before dropping, and on a white cultivar the contrast is sharper. Deadheading spent flower clusters encourages a second flush of bloom and keeps the tree looking tidy, though most gardeners find the natural drop acceptable. Rain-splashed petals on a patio or driveway can also create a temporary mess — something to consider if you are planting near a pool or outdoor dining area.
Bark is the other major ornamental feature, and it should factor into your cultivar choice just as much as flower color. ‘Natchez’ is famous for its peeling bark that reveals smooth layers of cinnamon and cream underneath — a feature that provides winter interest long after the leaves have fallen. ‘Acoma’ has lighter, grayish bark that is attractive but less dramatic. If you are drawn to crape myrtles partly for their bark, look for cultivars described as having “exfoliating” or “peeling” bark and plant them where the trunk is visible from a window or path you walk daily.
Comparing White Cultivars at a Glance
Because the variety names can blur together, here is a practical breakdown of the most widely available white crape myrtles and what sets each apart:
- ‘Natchez’: Large (20-30 feet), vase-shaped, outstanding cinnamon bark, strong mildew resistance. The default recommendation for anyone with space.
- ‘Townhouse’: Large but narrower and more upright than ‘Natchez.’ Good where you need height without as much lateral spread. Mildew resistant.
- ‘Sarah’s Favorite’: Large, upright form, good bark, widely available in the Southeast. Somewhat less mildew resistant than the National Arboretum hybrids but still reliable in most conditions.
- ‘Acoma’: Medium (10-12 feet), semi-weeping, graceful habit. Mildew resistant. Works well as a focal specimen or patio tree.
- ‘Glendora White’: Compact, older L. indica selection. No hybrid mildew resistance, so best in dry climates or with fungicide support.
- ‘Byers Wonderful White’: Compact, heavy bloomer. Like ‘Glendora White,’ an older selection without built-in mildew resistance.
Availability varies by region and nursery. In the Southeast, you will find the widest selection; in the Mid-Atlantic and parts of the Midwest, garden centers tend to stock the proven hybrids like ‘Natchez’ and ‘Acoma’ and fewer of the older or niche selections. Online specialty nurseries fill the gaps if you want something specific.
Newer Cultivars and the Dark-Foliage Trend
Breeding has not stood still since the National Arboretum’s heyday, and several newer white-flowered cultivars are worth knowing about. The Black Diamond and Delta Jazz series include white options with dark burgundy or near-black foliage, creating a striking contrast between flower and leaf. ‘Moonlight Magic’ is one example: white flowers set against deep purple-black foliage on a plant that stays around 10 to 12 feet. The visual effect is dramatically different from a traditional green-leafed white crape myrtle.
These dark-foliage cultivars are relatively recent introductions, which means long-term performance data is thinner than for something like ‘Natchez,’ which has been in the trade since the 1980s. Early reports suggest they handle heat and humidity well, but disease resistance can be more variable — some carry mildew resistance from hybrid parentage, while others are pure L. indica selections that may need more attention in humid climates. If you are drawn to the dark-leaf look, check the specific cultivar’s disease ratings rather than assuming all new introductions are improvements over older ones.
The surge of new cultivar names in garden centers can be confusing, and not all of them represent genuinely distinct plants. Some are rebrands or minor sports of existing cultivars marketed under new trade names. When in doubt, your state’s cooperative extension service often publishes crape myrtle trial results that cut through the marketing and report how cultivars actually perform in local conditions. Those trial reports are among the most useful resources for making a choice you will not regret ten years down the road.
