Woodland plants seem to be associated with spring but here are three that are at their best now.
They all prefer some moisture as well as shade.
Briggsia kurzii is a hairy leaved creeping rhizome from Sikkim. It grows to about 18" and the flowers resemble a yellow foxglove.
Roscoea 'Red Gurkha' has stout red flowers now. The foliage does not appear until quite late in the spring which makes it a perfect partner for a summer dormant plant.
Anemonopsis macrophylla is an elegant Japanese perennial and flowers for some weeks during July and August. Like the others it likes to be moist in the summer but never too wet during the winter months.
