Lavender Twist redbud

Sun

Full sun to partial shade; afternoon shade helps in hot, dry climates. A sunny, sheltered position encourages flowering in cooler regions.

Water

Moderate; keep the root area evenly moist while establishing, then water deeply during prolonged dry spells. Avoid waterlogged soil.

Soil

Well-drained loam, clay or sandy soil with some organic matter; tolerates mildly acidic to alkaline conditions.

Height

5-10 ft (1.5-3 m), depending on training

Spread

6-10 ft (1.8-3 m)

Flowers

Early to mid-spring; small lavender-pink to rosy-purple flowers cluster along bare branches before the leaves emerge.

Foliage

Heart-shaped green leaves, often bronze-tinted when young, turning yellow in autumn.

Growth

Slow to moderate

Growth rate

Slow

• Plant with the root flare at soil level and any graft union above the soil; choose the site carefully because established redbuds dislike being moved.
• Water deeply through the first two growing seasons whenever the soil begins to dry.
• Apply 2-3 in (5-8 cm) of organic mulch over the root area, keeping it clear of the trunk.
• If more height is wanted, tie a young upright leader loosely to a sturdy stake and check ties regularly; untrained growth tends to cascade.
• Remove shoots arising below the graft, and avoid routine feeding unless growth or a soil test indicates a deficiency.

Pruning. Prune lightly just after flowering to remove dead, damaged or crossing branches and shorten shoots that trail onto paths. Preserve the cascading framework and avoid heavy cuts into older wood.

Early spring

Check winter damage and loosen or replace any tight training ties.

Spring

Refresh mulch, keeping the root flare and trunk uncovered.

Late spring

After flowering, make any light shaping cuts and remove shoots below the graft.

Summer

Water deeply during dry spells, especially while the tree is establishing.

Autumn

Plant container-grown trees while the soil is workable and moist; in very cold regions, wait until spring.

Winter

Check supports and protect young trunks from rabbits or other browsing animals where needed.

• Use as a specimen in a small lawn or front garden, leaving room for the branches to spread.
• Place beside a patio or courtyard where its spring flowers and winter branching can be seen closely.
• Underplant with spring bulbs and low perennials that do not hide the cascading framework.
• Set at a woodland edge with light shade and a darker evergreen background to show off the flowers.

Garden styles it suits: Small-space, Cottage garden, Woodland, Romantic rose garden, Modern courtyard and Winter interest.

Plant it with: Snowdrops, Daffodils, Hellebores, Epimedium, Siberian bugloss and Japanese forest grass.

Wildlife: Spring flowers provide pollen and nectar for bees. Birds may eat the seeds, and the branching offers shelter, although this compact cultivar provides less habitat than a full-sized eastern redbud.

• Canker and branch dieback: prune affected branches back to healthy wood in dry weather, disinfect tools between cuts and reduce drought stress.
• Verticillium wilt: sudden wilting or branch death needs diagnosis; there is no reliable cure, and badly affected trees should be removed rather than replaced with another susceptible tree.
• Leaf spots: usually cosmetic; collect fallen leaves and avoid wetting foliage unnecessarily. Fungicide is rarely needed in a home garden.
• Scorch and drought stress: brown leaf edges or early leaf drop call for deep watering, mulch and, in hot climates, protection from harsh afternoon sun.

Not known to be toxic to cats, dogs, horses or people. No part is generally recognised as seriously poisonous, though eating large amounts of unfamiliar plant material can cause digestive upset.

• Eastern redbud (Cercis canadensis)

  The ordinary species forms a much larger, upright, spreading tree rather than a compact tree with strongly cascading branches.

• Ruby Falls redbud (Cercis canadensis 'Ruby Falls')

  Also weeping, but its leaves emerge deep burgundy-purple rather than becoming the green foliage typical of Lavender Twist.

• Weeping katsura (Cercidiphyllum japonicum 'Pendulum')

  Has opposite or nearly opposite leaves with finely toothed edges and lacks the conspicuous pink pea-like flowers on bare branches.

Cercis comes from the Greek name for a weaver's shuttle, referring to the seed pod's shape, while canadensis means 'of Canada' and Lavender Twist describes the flower colour and contorted, weeping growth.

Propagation. Usually propagated by specialist budding or grafting onto eastern redbud rootstock. Seedlings do not reliably retain the weeping habit or other cultivar traits.
