This grape juice color may be my favorite, but over the years they have self seeded and filled in lots of spaces, much better than I could have done planting them myself, and in every shade of pink, red, purple, lavender and anything in between.
I'm told that they also come in white, but I don't have any of those and the closest we've come is some very pale pinks or lavenders. Above is just a sampling of one part of the gardens at Lake Amanda.
These are considered a spring ephemeral since by the beginning of summer they will have totally disappeared. We plant them in gardens with things like hostas that will hide the bare spots. They are best in shade, at least they will last longer there, but we have them in sunny spots that they have chosen themselves and they seem to do all right there, but go dormant a lot faster. In the wild it is a woodland plant, and so those conditions are preferable. Grows in zones 4-8.
