This fragrant plant can grow in very dry soil in full sun, making it a great rock garden plant. Its common name is rose verbena and you can find it blooming right now along road sides, rocky bluffs, prairies, glades and sunny hillsides all over Missouri. Its sprawling low-growing habit lends itself to being used as a ground cover in rock gardens. It does spread and will take over an area (not quite like mint though). The flower color is simly stunning. From rose to purple shades.
