Cultivation

Cercis siliquastrum is propagated by seed, sown ripe in the cold frame or scarified and stratified. Semi-ripe cuttings can also be taken but require humidity and bottom heat.
Preferred cultivation conditions are either:
- deep, fertile, well-drained soil in partial shade
- full sun where the roots can be kept moist
Established plants benefit from an annual mulching of organic matter.
