Third time really is a charm.
Bought one in April 2016 from only local place selling this variety.
Slow start through May and I thought here we go again.
June changed all of that.
Sweet Tart is vigorous, prolific and the colors are pleasantly intense!
Some of the blooms are large, only slightly smaller than some of the "charm" petunia varieties.
Unlike many of my other callies, the flowers on Sweet Tart fade somewhat over the life span but never to the point where color is lost.
Just the new blooms are a powerful deep pink.
Would recommend for sure.
