A lovely woodland perennial native to eastern North America. Long-lived and tough despite its delicate appearance. Delicate, multiply divided foliage. Plants grow 8-10" tall and wide and should be planted about 8-10" apart.

The flowers are very double, and a soft clear pink that doesn't fade. Very long blooming, to six weeks. A spring ephemeral, the foliage dies down around early June.

Grow in moist acid well drained soil high in organic matter. Likes dappled shade.

This cultivar is slow to increase. After several years in the same spot, it can be divided as it's going dormant. The tubers are structured like a tiny dahlia's, and are divided the same way.

Hardy to Z4. Discovered by Oscar Shoaf growing in an old Minnesota cemetery.

A truly charming plant. Quite small and delicate, so plant where you can see it well. Does well in my zone 4a garden.
