One of the earliest spring flowers, sometimes blooming in the middle of the winter if there’s an extended warm spell, the Purple Archangel or Purple Dead-Nettle is everywhere. It is happy in open city lawns, and just as happy along a woodland trail in Bird Park, where we photographed these plants. The most decorative aspect of the plant is the contrast between the pale flowers and the dark leaves at the top of the stem; but the colors of the leaves are variable, and many plants show no significant purplishness at the top.
For a description of the species, see the Lamium purpureum reference page.
