A member of the Orchid Family of plants, although not rare.

Can be mistaken for: Lesser Twayblade (Neottia cordata), but that grows in bog and moors often hidden beneath Heather or in pinewoods and is much shorter at up to 10cm, with leaves more heart-shaped and the flowers are often dull reddish-green as well as more hooded.

Frog Orchid (Dactylorhiza viridis) can also be confused with Common Twayblade, but the latter has longer legs and the former sometimes has reddish-brown parts on the skyward side of the flowers when in drier places.

Distinguishing Feature : A single pair of broad but stubby leaves on the stem suspended above ground level and with no other leaves anywhere else. The flower looks like an alien with a long, split at the bottom, yellowish-green apron.

Likes to grown in grassy places and in woods. Seems to prefer lime.
