Folklore
Prunella comes from Brunella, after the German Bräune, an old name for quinsy, the throat abscess it was once taken for. In China the dried spikes are xia ku cao, the summer-withered herb, named for the way they brown at midsummer, and Chinese medicine gives them for swollen nodes in the neck and for goiter.
How to grow
A low perennial for sun or part shade and almost any soil that does not dry out completely. It creeps by rooting stems and self-sows into lawns, where it keeps flowering below mowing height. Bees work the flowers all summer. Cut the flowering tops when the spikes are in full bloom.
In the wild
Native all around the Northern Hemisphere, in Eurasia and North America alike, growing in lawns, meadows, roadsides, and woodland clearings.
