Minute Serissa or Snow Rose. I found this extremely dwarf Serissa in a small consignment bonsai nursery in Kawaguchi City, Saitama Prefecture, on the outskirts of Tokyo. Frankly I had to buy this selection as a small bonsai mounted on a rock as I could not get a "starter" plant. The leaves are one third the size of the species with likewise smaller flowers than the species. This will make an excellent subject for bonsai. With its tiny leaves and flowers, it is one of the best for making a really dwarf tree. There is a possibility that this cultivar could be 'Kyoto' because it is listed as getting to only 12" tall.
