Check out the exuberant blooms on this 'Chocolate Chip' ajuga! It is a favorite little groundcover that I like to use for the dark burgundy (almost black) foliage that sets off nearby plants. Sometimes I even forget that it actually blooms.
But right now it is a show stealer along the flagstone path near the front door in SJC. Mounds and mounds of bright purple spires about six inches tall are intermingling with the other blue and pink spring blooms. At first I forgot what it was until I looked closer because you can barely see the foliage anymore! The combination of cool weather and lots of rain seems to be just what makes this plant happy. Or else it thought it was going to drown and sent up lots of blooms to make seeds in a survival mode. Either way, it works for me!
