We grow Sinningia selovii and S. tubiflora here in NC in our full sun rock
scree. They have been in several years and have endured 9 degrees F (-13C)
with no problem (no mulch or snow cover). We also grow S. 'Tante', which
is an intermediate hybrid. We plan to put in another 30+ species this year
for trials. This was quite a surprise to us, but these seem far hardier
than their origin would indicate.

What about S. leucotricha? Has a bulb, sort of. My only gesneriad but one
of my favorite plants.
