About 20 years ago, I drove a very narrow roadway in northern Wales in search of Dibley’s Nursery. I had recently discovered the genus Streptocarpus, a houseplant that is closely related to African violets (now considered to be in the same genus). All my reading confirmed that Dibley’s was THE source in Britain, if not the world, for this plant. A visit was mandatory.
I was not disappointed. The complex of greenhouses was filled with Streptocarpus varieties in a rainbow of colors, everything except orange. It was a day I fondly remember. While I couldn’t transport any plants home with me, I’m now very pleased that the Miller Library has the 3rd edition of “Streptocarpus” by Rex Dibley. This book highlights many of the varieties the firm has introduced and much more.
There are over 150 recognized species and several of these are shown with photos from their natural setting in several locations in Africa. The most unusual have only one large leaf with the inflorescence growing out of the base. Some are monocarpic, blooming once, setting seed, and then dying. While these are more challenging to grow, I encourage all to try the easier hybrids that are widely available.
