Common Broom is a cheerfully flowering shrub that becomes smothered in bright yellow, butterfly-shaped flowers in May and June. The fine, broom-like green stems give the plant an airy look, even in winter. Broom is especially suited to dry, poor soil and enriches the ground with nitrogen through root nodules.

Care guide

Plant in full sun in well-drained, poor to moderately fertile soil. Broom needs no fertilising — the plant fixes its own nitrogen. Watering is rarely required; the shrub is exceptionally drought-tolerant. Avoid heavy, wet soils.

Pruning tips

Prune immediately after flowering by shortening spent shoots by a third. Never cut into old wood — broom does not regrow from it. Left unpruned, the plant can become bare at the base.
