Lamium maculatum, commonly called spotted deadnettle, is native to Europe and North Africa to West Asia. It is a mat-forming perennial ground cover that typically grows 5-8” tall but spreads indefinitely over time by sprawling stems which root in the ground as they go. Clusters of tiny, somewhat inconspicuous, two-lipped, red-purple (sometimes white or pink) flowers appear at the stem ends in late spring to early summer. Plants grow vigorously in optimum growing conditions, but are easy to control and are not considered to be too aggressive.

Genus name comes from the Greek laimos or lamos meaning throat in reference to the throat-like appearance of the corolla.

Specific epithet means spotted.

'Red Nancy' is basically the same as L. m. 'White Nancy' except for the differences in flower color indicated by the cultivar names.
