The terrestrial hellebore orchid, Epipactis helleborine, is native to Europe, but has been growing in Pennsylvania for many years. They come in various shades of green, yellow, pink and purple with flat, ribbed leaves. The dropping flower heads resemble the dropping flowers of Helleborus, known as the Lenten rose. (See some pretty ones at Gilmore Gardens from this past spring.)
Graham Rice says that he spread his orchid seeds about for interesting shade garden combinations. Sounds like a fun idea! Here is to more orchids at Havenwood.
