History

I used to have a small plant of S. leopoldii.  The second year it bloomed (2001), I put pollen of Sinningia sp. "Black Hill" on it, and got the hybrid I named S. 'Distant Lights', after a favorite piano piece.  The leopoldii parent died soon thereafter, but the hybrid plants have flourished.

In general appearance, the hybrid plants resemble "Black Hill", but have two horticultural advantages over it:

1. The plant is more compact, rarely exceeding 12 inches [30 cm] in height, and does not drop its lower leaves (the lower stem of "Black Hill" is often bare by autumn).
2. The hybrid has 2-4 flowers per axil, while "Black Hill" usually has just one (sometimes two).

Tuber

One year this plant had a rotten area on the tuber.  I cleaned out the mush, leaving this cavern behind.  It does not seem to inconvenience the plant.

Genetics

S. 'Distant Lights' has indeterminate growth habit, from its "Black Hill" parent; S. leopoldii is determinate.  I have crossed 'Distant Lights' with S. douglasii (also determinate), and got plants with indeterminate habit, despite the fact that only 1/4 of the ancestry is determinate.  This is consistent with the result from a completely different three-species mix.

Hybridization

As mentioned in the discussion of habit inheritance, I have crossed this plant with S. douglasii.  The hybrid plants have tubular flowers with some spotting, but are disappointing in both vigor and floriferousness.

Source of the Name

My hybrid names, few as they are, are allusions to ragtime piano music.  This one is more than an allusion -- it is the title of a piece written by Trebor J. Tichenor of Missouri.  Here is what he wrote about it:

"Distant Lights" is dedicated to the memory of my late wife, Jeanette. It was inspired by fond recollections of many evenings we gazed at the lights across the river, sharing flights of fantasy, hopes and plans for the future. The distant lights spread out across the Mississippi into Illinois seemed a nocturnal field of dreams. Those far away flickers inspired wonder at the many lives each one represented, and the stories they might tell.
