This is a fairly large flowered blue-purple that tends to be more prostrate growing from the start.
This one has a more upright compact habit early in the Spring (they all make neat mats by mid-summer). It was especially heavy flowering last year.
Two white flowered ones with purple undersides of the foliage.
And a completely white, with green foliage - this one rebloomed fairly early last Fall.
Wouldn't it be great to get pretty foliage and flowers and rebloom all combined into one plant!
