Sinningia macrostachya x leucotricha: sure looks like it

Jon Dixon gave me a seedling of this plant.  It was from seed which he collected from his plant of S. macrostachya.  We both agree that it isn't a selfing, however, and our best guess at the pollen parent is S. leucotricha, since the plant has something of the silvery quality that the latter species has.

Horticultural aspects

Hybridizer Hummingbirds
Fertility This hybrid sets seed every year, although I have not sown any.  There is every reason to expect that it is fertile.
