Geranium nodosums, which cross with each other creating a wonderful colour range. This perennial plant is perfect for dry shade but will take some sun. The different lilacs and deep pinks aren't known until your plant flowers (the white flower is Silverwood - also for sale). 
Organically grown by Pauline and correctly identified.
Please look at all of Paulines photographs of this perennial.
It copes well with part shade and when established tolerates full sun!
You will receive your quality established organic plant in a 9cm recyclable grey pot similar to that shjown in the photo, your plant was propagated last year and it has never been in a protected environment but has been kept outside.
