Hi Dave - welcome to ATP! (belatedly!) yes I got some of mine at violet barn also, and then if you look up your local Gesnariad society they may have meetings near you, in which case there are always folks happy to share either their own hybrids which can be fun, or leaves for you to start babies with - which everyone says is really easy...mine start but then die out, mostly (the babies not the plants!) Gesnariads include african violets, Streps, sinningia and other plants as well (fuzzy plants with blooms!)
Here is the website for National Gesnariad society
