Frosted Jade

Primulina yungfuensis grown by Bill Price

            Common names and marketing names are a part of Horticulture.  They evolve and there is no stopping them.

            Primulina yungfuensis has tremendous potential as a commercial plant, but we need a better name if it will be talked about.

            Several names have been proposed to me and the consensus is that Frosted Jade should be the one. Jade has a Chinese connection and the leaf has a dark green color.  If you look at yungfuensis with the sun shining on it, the silver variegation on the dark green jade sparkles like frost looks on grass.

Hybrids get nice English word names that have some significance to the hybridizer who usually gets to name his selected new releases.

Species have Latin names but can be designated with a cultivar name, if there is variability in the collected specimens.  Sometimes, a geographical name will be added to a species name to distinguish it from other clones of that species.  Occasionally, some named species cultivars are determined, by taxonomist, to be different enough to be named a different species.

            While all of this is going on, common names and marketing names are valuable to keep the plant world turning and the horticulture trade moving.

            Through a technicality, the botanical name cannot be Primulina yungfuensis ‘Frosted Jade’.  By adding the cultivar name, it implies that there are other different clones of the yungfuensis species.  Since at this time there is only one known clone of yungfuensis in North America, there cannot be any distinction.

            By announcing my marketing name of Frosted Jade, I hope that it becomes the common name for Primulina yungfuensis.

            In casual conversation it will be much easier to ask:  “How’s your Frosted Jade doing?” then saying: “How’s your Primulina yungfuensis doing?”

            Will Frosted Jade gain acceptance? --- The market will decide.


  1. I recently bought a small plant of P. yungfuensis from a seller on Ebay. Imagine my surprise when I finally got around to looking carefully at the label and realized the plant originally came from you! Thanks!

  2. This is the variety I have... it's looking just a little sad, I can't quite figure out how much sun it needs and I think I was overwatering until recently. New growth, baby leaves, but there seem to be a good amount of leaves dying.
