Bloom period
Care guide
Plant in full sun in well-drained soil. Once established, the plant is very drought-tolerant thanks to a deep root system. Do not transplant — the long taproot makes this virtually impossible. No feeding needed; as a legume, the plant fixes its own nitrogen.
Pruning tips
Leave the decorative seed pods in place through winter for garden interest. Cut dead foliage at the base in late autumn or early spring. The plant needs no further pruning and grows compactly without staking.
