Natchez crape myrtle

Sun

Full sun, ideally at least 6 hours of direct sun daily; shelter from cold winds in cooler climates.

Water

Water regularly while establishing; moderately drought-tolerant once established, but flowers better with deep watering during prolonged dry weather.

Soil

Well-drained loam, clay or sandy soil; prefers moderately fertile, slightly acidic soil but tolerates a range of pH levels. Avoid waterlogged ground.

Height

20-30 ft (6-9 m)

Spread

15-25 ft (4.5-7.5 m)

Flowers

Large clusters of white, crinkled flowers from midsummer into early autumn; the season is shorter in cooler climates.

Foliage

Glossy green, oval leaves emerge relatively late in spring and turn orange to red in autumn; colour varies with climate and growing conditions.

Growth

Moderate to fast in warm climates with adequate moisture.

Growth rate

Fast

• Water deeply through the first two growing seasons whenever the root zone starts to dry.
• Spread 2-3 in (5-8 cm) of organic mulch over the root area, keeping it clear of the trunks.
• Feed lightly in spring only if growth is weak or soil is poor; excess nitrogen encourages leafy growth rather than flowers.
• Allow room for the mature crown rather than planting where regular size reduction will be needed.
• In colder areas, plant in spring in a sheltered, sunny position; protect young trunks from physical damage.

Pruning. Prune in late winter or early spring, removing dead, crossing or damaged branches and unwanted basal shoots while preserving the natural framework. Do not top the tree or cut its main branches back to stubs; flowers form on the current season's growth without this treatment.

Late winter

Inspect the bare framework and remove dead, rubbing or poorly placed branches.

Spring

Plant in cooler regions once severe frost has passed, then water thoroughly and mulch.

Late spring

Allow time for late leaf emergence before deciding that a branch has died; remove basal shoots if maintaining a clear-trunked tree.

Summer

Water deeply during prolonged drought and inspect shoots and bark for aphids or scale.

Early autumn

Avoid nitrogen feeding or hard pruning that could encourage tender growth before winter.

Late autumn

Refresh mulch where needed, leaving the trunks uncovered.

• Use as a lawn specimen where the spreading crown and peeling bark can be seen from the house.
• Plant beside a sunny terrace with enough clearance for its mature canopy; expect some fallen flowers and leaves.
• Repeat along a broad drive or boundary to create a loose avenue with summer flowers and winter bark interest.
• Underplant with ornamental grasses, catmint or salvia for a sunny border with contrasting fine textures.

Garden styles it suits: Southern, Traditional, Modern courtyard, White garden, Mediterranean and Winter interest.

Plant it with: Catmint, Autumn sage, Switchgrass, Lilyturf, Society garlic and Russian sage.

Wildlife: Flowers provide pollen for bees and other visiting insects, although they offer little nectar. Branches provide perching and nesting cover for small birds.

• Poor flowering: shade, cool summers or excess nitrogen are common causes; provide the sunniest, warmest suitable position and avoid unnecessary feeding.
• Aphids and sooty mould: aphid honeydew supports a black surface coating; wash small infestations off with water and conserve ladybirds and other predators.
• Crape myrtle bark scale: in affected parts of the United States, white felt-like insects on bark can cause heavy honeydew and sooty mould; confirm identification and follow local extension guidance for treatment.
• Powdery mildew: Natchez is resistant, not immune; give the crown good airflow and full sun, and avoid excessive nitrogen.

Not known to be toxic to cats, dogs, horses or people. No part is recognised as a significant poisoning hazard, but the plant is not intended for eating.

• Acoma crape myrtle (Lagerstroemia 'Acoma')

  Also has white flowers, but stays much smaller and has a distinctly spreading, arching habit rather than developing the tall framework of Natchez.

• Japanese crape myrtle (Lagerstroemia fauriei)

  Shares white flowers and richly coloured peeling bark, but generally has smaller flower clusters and can become a larger tree. Young plants can be difficult to distinguish without a reliable label.

The cultivar name 'Natchez' honours the Natchez Native American people.

Propagation. Take softwood cuttings in late spring or semi-ripe cuttings in summer and root under humid conditions in a free-draining medium. Seedlings will not reliably retain the characteristics of Natchez.
