Genista lydia comes from the Balkans, Turkey, and Syria, where rocky, poor soils and dry summers produced a shrub of striking adaptability. Growing only one to two feet tall with arching, multi-branched stems, it covers itself in bright yellow pea-like flowers in spring and remains structurally attractive through the rest of the year even without bloom. The genus name has a distinguished lineage: it derives from the Latin planta genista, the plant from which the Plantagenet kings and queens of England took their name. In the garden, the shrub carries its history lightly.

Full sun and well-drained, preferably sandy or alkaline soil are the main requirements. Lydia broom fixes nitrogen, which helps explain its contentment in poor soils where other shrubs struggle. It tolerates drought, heat, salt, and deer, and needs pruning only once a year immediately after flowering. Clay soils and wet conditions are its few genuine dislikes. For xeriscape plantings, dry stone walls, sloped beds, or any sunny spot where a low, billowing shrub with extraordinary spring color would be welcome, few plants of comparable size give as much.
