The Story

Plant Bio

Lespedeza thunbergii, Thunberg's bush clover, is a deciduous shrub from the eastern Himalaya through southern China and temperate East Asia. It throws up arching, almost fountain-like stems 3 to 6 ft high and wide each year, clothed in blue-green trifoliate leaves. Rose-purple pea flowers crowd 6 in racemes in late summer and autumn.

It behaves more like a herbaceous perennial than a shrub, dying back hard in cold winters and regrowing from the base each spring. Flowering comes in August and September when little else of its size is in bloom, and the weight of flower bends the stems into a fountain. Nitrogen-fixing roots suit poor, dry ground.

Uses & Benefits:

Ornamental UsesLong arching sprays of rose-purple pea flowers in late summer and autumn, over fine blue-green trifoliate foliage.
Practical UsesUndemanding on poor, dry soil, fixes its own nitrogen, and rebuilds its full size from a hard spring cut every year.
Ecological BenefitsButterflies and hummingbirds work the flowers at a point in the season when nectar is becoming scarce.

Planting

How to Grow

  1. Plant in full sun or light shade in ordinary well-drained soil.
  2. Allow 5 to 6 ft of space for the arching stems to fall into.
  3. Water through the first season, then only in real drought.
  4. Skip the fertiliser; it fixes its own nitrogen.
  5. Cut all stems to 6 in above the ground in early spring.
  6. Remove self-sown seedlings before they establish.

Pro Tip

Cut the whole plant to a few inches every spring: flowers come only on new wood, and old stems give a sparse, sprawling display.

Care Guide

Do

  • Site it where the stems can arch out freely 🌿
  • Cut it hard to the base every spring ✂️
  • Let it carry the late-summer border after other shrubs finish 🌸
  • Leave the soil lean; it fixes its own nitrogen 🌱

Don't

  • Do not feed it; rich soil gives floppy growth and fewer flowers ❌
  • Do not treat winter dieback as a problem; it is normal ❌
  • Do not let seedlings spread into rough ground unchecked ❌
