Yellow Broom

Yellow Broom (Cytisus decumbens) is a very low, prostrate shrub that spreads along the ground and brightens sunny sites with rich yellow flowers in late spring. Kew accepts the species as Cytisus decumbens and places its native range in south-central and southern Europe. ## Form and Seasonal Display The [Trees and Shrubs Online account](https://www.treesandshrubsonline.org/articles/cytisus/cytisus-decumbens/) describes the plant as one of the most prostrate brooms in cultivation, with growth laid over older stems. Bright yellow flowers appear in May and June. Kew's [Plants of the World Online record](https://powo.science.kew.org/taxon/489710-1) confirms the accepted species name and European range. ## Siting Use it where its low outline can be seen, such as a sunny rock garden or the front of a dry-stone edge. The species account specifically recommends full sun and a rock-garden position. Its spreading form makes it useful as a low ground-covering accent, but leave room for the plant to extend without covering smaller neighbors. ## Maintenance Keep the plant in a sunny position and check the edges as its prostrate growth develops. The cited species profile gives flowering and siting information but no detailed pruning schedule, so avoid cutting into old woody growth without local species-specific advice.
