Spiranthes spiralis, commonly known as Autumn Lady's-tresses, is the latest-blooming native species of orchid, blooming in August and September. It is characterised by a spiral inflorescence produced after the leaves have died down. The inflorescence can be very small (as little as 50mm high) especially in short grazed grassland. It occurs most frequently in close cropped grassland overlying chalk or limestone.

[edit] Distribution

The area of distribution is from the Mediterranean zone of Northern Europe northwards and westwards to the Western Himalayas. In Great Britain and Ireland its northern-most occurrence is on the Isle of Man. It has never been found in Scotland.[1] In Ireland it has been recorded from County Sligo.[1]
