Harvest Tips

This ornamental shrub is not typically harvested for culinary or medicinal use. Cut flower stems in winter for indoor arrangements; buds will open indoors in warmth. Prune lightly after flowering in spring to maintain compact form; never cut back to bare wood.

Fun Facts

  • 🌱 Peter Sparkes is a hybrid between Erica darleyensis and Erica carnea, combining the winter hardiness of one parent with superior flower production.
  • 🌱 The double pink flowers are sterile, meaning the plant directs all its energy into spectacular blooms rather than seed production.
  • 🌱 This cultivar was named after Peter Sparkes, a noted British heather breeder and enthusiast who developed many popular Erica cultivars.
