Dibley's Nurseries founder Rex Dibley said: "It is hard to believe it is now forty years since I turned a hobby into a small business. We have come a long way in that time. In 1976 Streptocarpus were little known and I decided they were underrated and deserved to be more popular and also they were great fun to propagate, hence the Nursery."
Polka-Dot Purple, bred by Rex's daughter Lynne Dibley, will be available to garden centres as a 12cm pot plant from Easter onwards and will retail between £11.99-£12.99.
Dibleys received a record number of 12 RHS Gold Medals in 2015, and were awarded their 26th Chelsea RHS Gold Medal.
