Heart-flowered Marsh-orchid, Dactylorhiza cordigera

One of many marsh orchids, Dactylorhiza cordigera is distinguished by the heart-shaped lip of the flower from which are derived both its common and scientific names.

Description

This orchid has very darkly spotted leaves and dark purple flowers. The plant grows to around 40cm tall and is very robust, with flowers of dark purple patterned with even darker purple loops and streaks. The lower lip is distinctly heart-shaped, as can be seen from the close-up below.
