Stylophorum diphyllum - Celandine Poppy
Excellent plant for the shade garden. The bright yellow flowers really stand out in a dark corner. Blooms heavy in spring, then has sporadic blooms throughout the summer. Spreads very well to make a ground cover. Prefers rich woods soil, does not like much direct sun.
