Purple Deadnettle Lamium purpureum LinnaeusNon-native  Synonyms: Purple Henbit, Red Dead Nettle, Red Deadnettle.

Status:

"Naturalized from Europe; Newfoundland, Nova Scotia, west to Minnesota, south to South Carolina, West Virginia, Ohio, Indiana, Illinois and Missouri" (Reed, 1964).

Description:

As is typical of the Mint Family, Purple Deadnettle has square stems, opposite leaves, and five-petaled flowers. It is low-growing and can easily be confused with two other low-growing mints, Henbit and Ground Ivy. Purple Dead-nettle has purple in the leaves of the upper stem. Its leaves have petioles (stalks) and are deltoid (triangular) in shape, with serrate margins. In contrast, Henbit's leaves have no petioles, and each pair of leaves encircles the stem. The leaves have crenate to shallowly lobed margins. Ground Ivy leaves have long petioles and are kidney-shaped to round, with crenate margins.

Where to find:

This common, low-growing species can be found along roadsides and in yards, fields, and disturbed soil throughout Maryland.

There are 668 records in the project database.
