The lovely Enchanter’s Nightshade (Circaea lutetiana) is a plant native to the United Kingdom that appears weak and tender but can be a pesky weed once it establishes itself in the garden.
What makes this plant so invasive are the thin, spreading rhizomes that creep around the garden, allowing it to cover large areas. The plant belongs to the Onagraceae family. There are two recognized subspecies[1] (or varieties): the North American species is the variety Canadensis (also referred to as Circia canadensis), and its Eurasian counterpart is the variety Quadrisulcata (Circia quadrisulcata).
