<—do you see them? they aren’t easy to find!
Liparis liliifolia grows in a large variety of habitats, wet and dry, soils more or less acidic. But mostly it likes disturbed areas, for example where there’s more sunlight due to a tree falling; however, populations will decline after a few years as the forest canopy closes in again.
Like showy orchis and pink lady’s slipper, it sports two basal leaves. The single flowering stem can bear up to 30 flowers.
Currently the Maryland DNR ranks large twayblade S2S3 (S2=imperiled/state rare; S3=vulnerable/watchlist). It’s endangered in Connecticut, New York, and Rhode Island, and threatened in Massachusetts and Vermont.
Common names include large twayblade, purple twayblade, lily-leaved twayblade, brown widelip orchid, russet-witch, and mauve sleekwort.
