Purple deadnettle

Description:

Also called the red deadnettle or purple archangel, this is a herbaceous flowering plant native to Europe and Asia; it is listed as an invasive species in some parts of North America. Young plants have edible tops and leaves, good in salads or in stir fry as a spring vegetable. If finely chopped, it can also be used in sauces, but there is little to recommend about its flavor.

Habitat:

Alongside an enclosure in a wildlife sanctuary
