Purple Deadnettle, Red Deadnettle, Purple Archangel - Lamium purpureum


Family: Lamiaceae – Mint family Genus Common Name: Deadnettle Native Status: Introduced
Lamium purpureum - Purple Deadnettle, Red Deadnettle, Purple Archangel. The deadnettles are native to Europe and Asia, but are now widely naturalized in the United States. As with many non-native species which have become widespread in the U.S. Purple Deadnettle blooms early. A similar species is Henbit - L. amplexicaule - The middle and upper leaves of L. amplexicaule do not have petioles while those of L. purpureum have petioles on all leaves, although the upper ones are quite small. The leaves of Henbit (L. amplexicaule) are also typically smaller than those of Purple Deadnettle.
