About

Genista radiata is a mat-forming, well-branched shrub in the pea family (Fabaceae) with deciduous foliage and a concentrated spring flowering period. It performs best in full sun on well-drained loam with a neutral pH and tolerates exposed as well as sheltered sites. Classified H5 (hardy), it suits many UK locations and is particularly at home on slopes, gravel or in courtyards. Flowers appear April to June.

About the genus

Genista is a genus of flowering plants in the legume family Fabaceae, native to open habitats such as moorland and pasture in Europe and western Asia. They include species commonly called broom, though the term may also refer to other genera, including Cytisus and Chamaecytisus. Brooms in other genera are sometimes considered synonymous with Genista: Echinospartum, Retama, Spartium, Stauracanthus, and Ulex.

In the garden

Genista radiata is a mat-forming shrub in the Fabaceae with a compact, well-branched habit and deciduous leaves. Its main ornamental interest comes from the spring display: flowers appear from April to June, providing a clear seasonal focus before the plant drops foliage for winter. Position the plant in full sun in a free-draining loam with neutral pH; good drainage is important, so avoid heavy, waterlogged soils. It tolerates both exposed and sheltered situations and should be sited on south-, east- or west-facing aspects to maximise flowering. The hardiness rating H5 means it is classed as hardy in the UK and will withstand typical winter conditions in most areas. Genista radiata fits well where a low, mat-forming shrub is required: city and courtyard gardens, gravel and rock gardens, banks and slopes, and informal or cottage borders. Its spreading habit suits bank stabilisation or a front-of-border position where the spring flowers are visible close to eye level. Place it where the spring display can be appreciated, since its main season of interest is April to June.
