Striking, deep pink blooms fading to blue in profusion late February to April! 15-18" well behaved clump for part shade, good soils…lovely with primulas, pulmonaria. Prefers moisture during growth and bloom season. This is a RARE and underused beauty, everyone that sees it in bloom falls in love with this plant. Quite VETCHING!
