Western redbud

Sun

Full sun for best flowering; tolerates light shade.

Water

Water deeply during establishment, letting the soil dry partly between waterings. Established plants tolerate summer drought and usually need only occasional deep watering during prolonged dry spells.

Soil

Well-drained sandy, loamy or gravelly soil; tolerates clay if drainage is good. Avoid persistently wet ground.

Height

10-20 ft (3-6 m)

Spread

10-20 ft (3-6 m)

Flowers

Early to mid-spring, before the leaves open; clusters of magenta-pink, pea-shaped flowers along bare branches.

Foliage

Rounded to kidney-shaped, blue-green leaves, often bronze when young; usually yellow in autumn, sometimes with orange or red tones. Flattened seed pods may persist into winter.

Growth

Moderate when young, slowing with age.

Growth rate

Slow

• Plant in a permanent position with good drainage; established plants dislike root disturbance.
• Water deeply through the first two growing seasons, allowing the upper soil to dry between waterings.
• Reduce summer irrigation once established; keep it away from frequently watered lawns.
• Apply 2-3 in (5-8 cm) of mulch, keeping it clear of the stems.
• Do not routinely fertilise; excessive feeding encourages leafy growth rather than flowers.

Pruning. Prune lightly just after flowering to remove dead, damaged or crossing branches and, if wanted, select a few main stems. Avoid hard pruning and unnecessary large cuts.

Autumn

Plant in mild-winter regions while the soil is still warm, and water thoroughly.

Late winter

Check drainage and inspect bare stems for dead wood or sunken, damaged bark.

Spring

Plant in colder regions after the ground is workable and severe frost has passed.

Late spring

After flowering, remove crossing branches and unwanted basal shoots if training a small tree.

Summer

Check young plants regularly and water deeply when the root zone begins to dry; avoid frequent shallow watering.

Late autumn

Refresh mulch without covering the stem bases, and collect ripe pods if propagating from seed.

• Use as a small specimen tree beside a terrace, leaving room for its broad crown.
• Keep its natural multi-stemmed form in a California native shrub border.
• Combine with evergreen shrubs so the bare-branch spring flowers stand out.
• Plant above low, drought-tolerant groundcovers in a sunny gravel garden.

Garden styles it suits: California native, Mediterranean, Desert / xeriscape, Wildlife garden, Pollinator garden and Dry gravel garden.

Plant it with: California lilac, Manzanita, Cleveland sage, Deer grass, California fuchsia and California poppy.

Wildlife: Spring flowers provide pollen and nectar for bees, including native bees. The branching canopy offers shelter for small birds.

• Root rot in wet soil: improve drainage before planting and avoid frequent summer irrigation.
• Canker and branch dieback: remove affected branches back to healthy wood in dry weather, disinfect tools between cuts and reduce drought or waterlogging stress.
• Verticillium wilt, causing sudden branch wilt: seek a diagnosis, remove dead wood and avoid replanting susceptible trees in confirmed affected soil.
• Leaf spots in damp conditions: clear fallen leaves, improve airflow and keep irrigation off the foliage; minor spotting rarely needs treatment.

Not known to be toxic to people, cats, dogs or horses. Species-specific safety information is limited, so do not treat leaves, bark, pods or seeds as food or livestock feed.

• Eastern redbud (Cercis canadensis)

  Usually has larger, distinctly heart-shaped leaves with pointed tips; western redbud leaves are generally rounder, with blunt or notched tips.

• Judas tree (Cercis siliquastrum)

  Often develops into a larger tree with conspicuous flower clusters on its trunk and older branches. Its rounded leaves overlap in appearance, so check the plant's identity rather than relying on leaves alone.

• Chinese redbud (Cercis chinensis)

  Typically has more pointed, heart-shaped leaves and very dense flower clusters; western redbud has rounder, often blue-green leaves.

The species name occidentalis means 'western', referring to its western North American distribution, while redbud describes the reddish flower buds.

Propagation. Grow from seed collected from mature brown pods. The hard seed coat usually needs scarification followed by a period of cold, moist stratification; germination can be uneven. Transplant seedlings while young to minimise root disturbance.

Accepted botanical name
