Hi, I have been digging over this small dappled shady area and i'm wondering what to put in here. I would love a potentilla like the one in the bottom pic but thats in full sun so not sure it would be suitable. I want something to add more colour in the spring/summer months. Also the Rozanne's x 3 in the pic were put in last summer as baby's and I know they spread so how long before they get overcrowded. I was thinking of leaving one where it is and finding another spot for the other two maybe even putting them in large pots. Thanks..
