This is one of our earliest perennials to bloom. The leaves come up, very dark, sometimes almost black, long before the last frost and once if warms up a little it will be covered with shiny yellow flowers, buttercup color, which is appropriate since this is a buttercup. If you plant it be sure to remember where, since it will go dormant once the heat sets in. It seems to like rock gardens and mostly full sun, though I do have some in other places. At some point it seems to self seed and I find babies in other places. With this plant, I never find that to be a problem since it is so pretty and not very big even as a full sized plant, probably 8 inches across on this one and 5 inches tall. More of the buttercups tomorrow.
