Self heal

Self-heal (Prunella) - This handsome and vigorous plant P. grandiflora is readily distinguished by its large flowers. There is a white and a purple variety, both handsome plants, thriving in almost any soil. In winter they are apt to go off on the London clay, at least on the level ground, but are well suited for mixed borders, banks, or copses. P. Webbiana is a good garden form, making a thick green carpet, with spikes of rosy-purple flowers. Europe.
