Greater butterfly orchid

A striking British and European native with scented white flowers (up to about 24), up the stem with a green tint, appearing from June to August. Each flower has a downward-pointing lip. In the wild it grows in pastures and on grassland, and is best grown in a wild garden or a spare part of a cottage garden. It'll spread, creating a beautiful, highly distinctive effect. A good and very similar alternative is P. bifolia.
