Giant Stream Orchid likes it moist. I have seen Epipactis gigantea growing on a
clump of soil in the middle of a stream in full sun. The most robust group of
plants was found in deep shade on a seep. The Giant Helleborine will grow with
considerably less water, but Epipactis gigantea needs some and regularly. The
Giant Stream Orchid blooms in mid to late spring. Epipactis gigantea goes
dormant in the winter. I make divisions of my plants at this time. Epipactis
gigantea seems to prefer moving water. Plants absolutely do better without
chlorinated water. You can get most of the chlorine out of your water by
leaving it exposed to the air for 24 hours or more. I fill my watering can as I
complete my watering so it can outgas the chlorine before I water the next time.
Post has included Epipactis gigantea in a collectable series of stamps.
