Henbit Deadnettle (Lamium amplexicaule) vs. Purple Deadnettle (Lamium purpureum)

These introduced weedy annuals, both low-grade invasives in much of North America, overlap greatly in range and habitat, and are visually similar. They can be easily distinguished by close examination of the arrangement of leaves and flowers near the stem tips. L. purpureum is slightly more shade-tolerant, whereas L. amplexicaule has a slightly more extensive range and ranges into slightly drier conditions.
