Purple Dead-Nettles - Lamium purpureum

The most distinctive characteristic of Purple Dead Nettle is the purple tint of the young leaves at the top part of the stem. The leaves have fine hairs, are green at the bottom and shade to purplish at the top. The flowers are bright red-purple, with a top hood-like petal, two lower lip petal lobes and minute fang-like lobes between.

Purple Dead-Nettles were introduced to Wisconsin. They are considered an adventive species. An adventive species is a species that has arrived in a new locality. It may have had help from humans as an introduced species or it may not.

Other Names: red dead-nettle, purple archangel. Lamium: the ancient Latin name for the mints.
