I love this primrose that grows so well in our area. They are vigorous and transplant easily. They show such enthusiasm even in drought that I enjoy letting them spread. This is one of my favorites, but I do cut them back after blooming since they get straggly and unattractive. Not to worry – they bounce back next spring.
