Primula vulgaris subsp. sibthorpii is actually a form of our native primrose found in the Balkans. A delightful little plant and so easy to grow. Starting to flower, and WOW, does it flower, from mid February. Not at all weak like some of the Primulas it is vigorous, low growing perennial and very tough and reliable. Large soft lilac-pink flowers with a distinct yellow eye. Ideal to grow as ground cover under deciduous trees and shrubs in any soil as long as the soil is not too dry.
Our plants are divisions from a very reliable form and not seedlings.
There is an excellent blog by John Grimshaw for further reading. Cultivation Notes
