Cytisus ×praecox, commonly known as Warminster broom, is a hybrid evergreen shrub found in open woodlands and scrub areas in Europe. It typically grows to a height of 4-6 feet (1.2-1.8 meters) and a width of 5-6 feet (1.5-1.8 meters). This hybrid plant is recognized for its arching stems and small, trifoliate leaves. During late spring to early summer, Warminster broom is adorned with profuse pea-like, yellow flowers that are highly ornamental and attract pollinators. The flowers are followed by small, brown seed pods.

Warminster broom is valued for its vibrant yellow flowers and its ability to adapt to poor soils, making it a popular choice for embankments, borders, and as a ground cover in sunny areas. It thrives in well-drained soils and requires full sun to flower abundantly. Once established, it is drought tolerant and requires minimal maintenance. However, gardeners should be cautious as it can become invasive outside its native range, spreading by seed and root suckers. Regular pruning after flowering can help maintain its shape and prevent unwanted spread.CC BY-SA 4.0
