Native of Greece and the islands of the Grecian Archipelago; introduced to the Hammersmith nursery of Messrs Lee in 1788. It is a rather tender plant, and will survive only our mildest winters without protection. But for the warmer counties few more charming dwarf shrubs could be found. Even in cooler districts it is well worth the little protection it requires. Flowers from late July to September.
