Broom (Cytisus)

Cytisus is a genus of broom shrubs in the pea family, Fabaceae; USDA GRIN-Global lists “broom” among its common names. The genus-level record is a guide to the group, while mature size, season, flower color, and site needs should be chosen from the individual species or cultivar. ## Group Characteristics The [Royal Horticultural Society](https://www.rhs.org.uk/plants/5254/cytisus-scoparius/details/) describes Cytisus shrubs as ranging from prostrate to erect, with deciduous or evergreen foliage and pea-like flowers that may appear in spring or summer. This variety of forms is why the genus name alone does not predict the finished plant's height or spread. The [USDA GRIN-Global genus record](https://npgsweb.ars-grin.gov/gringlobal/taxon/taxonomygenus?id=3337) confirms the genus placement in Fabaceae and the common name broom. ## Choosing a Broom Use the child species or named selection when planning spacing and seasonal color. Individual records can differ substantially: for example, Cytisus decumbens is a low, prostrate species, while other brooms form taller shrubs. Check local guidance for the exact selection before applying species-level hardiness, pruning, or water recommendations to the genus. ## Maintenance Match care to the identified species and its site. For many garden brooms, the RHS recommends full sun and well-drained soil, but those directions come from its C. scoparius profile; confirm requirements for the specific broom before planting.
