Purchased several years ago from http://www.violetbarn.com/ it has continued to delight me - especially when it breaks out with flowers in two different colors in different parts of the plant. Note both the lavender and pink flowers.
Lovely! I used to grow African violets years ago. Even joined an African violet club and was prepared to enter a competition as I had fussed over a couple plants and pinned the leaves to make them line up perfectly and the day before the show, I was checking the plant to find it had aphids... a big no-no for competing. That was the end of that endeavor. Your trailing violet is obviously very happy!
