It can be cut back after flowering to promote more compact growth, but does not require deadheading. (Be sure to wear gloves when pruning this plant as the milky white sap can cause irritation to sensitive skin.)
It may be slow to establish and may not look very impressive in the first year or two, but is long-lived and mostly pest free. It is not favored by deer or rabbits. Because the clumps expand very slowly it usually does not require frequent division. It is best to wait until spring to cut the stems from the previous year’s growth back to the ground.
This planting is in the 9 Grace garden .
