Epipactis thunbergii is a broadleaf deciduous perennial orchid with green foliage. In spring and summer magenta, orange and yellow flowers emerge. Grows well with mostly sun - mostly shade and even moisture - regular water. Does well in well-drained soil. A good option if you're seeking something verticillium wilt resistant.
