Sinningia macrostachya x leucotricha: sure looks like it

msty x leuc
  1. Feature table

Jon Dixon gave me a seedling of this plant.  It was from seed which he collected from his 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

From seed A couple of years to bloom, under my conditions
Hardiness Has tolerated 26F (-3C), in shelter, in my yard
Recommended? Not a bad plant, interesting for hybridizing potential

Hybridization

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.

Nectaries Two, separate, dorsal, usually with a blob of nectar remaining on each one after the corolla falls (like the S. macrostachya parent).
