Meadow Sage ‘Caradonna’ (Salvia nemorosa). The helpful label tells me: One of the least demanding, most satisfying perennials in the garden. Oh yes, yes, yes, this is a plant for me. Into the canoe garden with it. The purple blooms look great behind the bright yellow Moonbeam Tickseed. It can handle sun to part shade and as a bonus, this plant attracts butterflies.
