Sinningia "Pink Eumorpha"

Sinningia Pink eumorpha
  1. Compared to S. eumorpha
  2. Feature table

First things first.  "Pink Eumorpha" is not a legitimate hybrid name, since hybrid names cannot include species names or imply that they are a variety of a species.  The 1988 Sinningia Register has an entry for this plant, showing that its first listing was in a 1963 Kartuz catalog.  The entry is followed by the dread word "coderejected".

Despite its unknown origin and nomenclatural disgrace, the plant is still attractive and easy to grow, definitely easier than its putative species relative.  It produces lots more flowers than S. eumorpha, and while most people would prefer the pure white-flowered eumorpha to either "Pink Eumorpha" or the lavender-tinged eumorpha, I much prefer the flowers of "Pink Eumorpha" to any S. eumorpha with lavender in it.

Actually, apart from the green leaves and the name, there isn't all that much to connect "Pink Eumorpha" with S. eumorpha.  "Pink Eumorpha" has also been compared with S. 'Anne Crowley', but they are clearly not the same.  The following table compares the three varieties.
