Summary

Erica ×watsonii, commonly known as Watson’s Heath, is a naturally occurring hybrid shrub that is evergreen and typically found in heathlands and moorlands. It is native to Western Europe, particularly the United Kingdom and Ireland. This moderate-growing plant reaches heights and widths of approximately 1.5-2 feet (0.46-0.6 meters). Watson’s Heath has a dense, mounding form with needle-like foliage. Its flowers are bell-shaped, pink, and notably showy, blooming profusely from late spring to mid-summer, attracting pollinators such as bees.

Watson’s Heath is valued for its year-round foliage and spring-to-summer floral display. It is used in rock gardens, as ground cover, and in borders for its texture and color. While it prefers acidic soils, it can adapt to loam or sandy soils with good drainage. It thrives in full sun to part shade and requires consistent moisture, but it is drought-tolerant once established. There are no major disease problems, but it can be susceptible to root rot if overwatered. It is not known to be invasive and does not have aggressive roots. Pruning after flowering can help maintain its compact shape and encourage more blooms.CC BY-SA 4.0
