Sinningia tubiflora

In L.A. it was very easily grown in the ground, going dormant each winter
without temperatures approaching 0°C and then re-sprouting with blooms in
early summer. Summers had plenty of heat and they were grown in full
intense sun. They didn't seem to mind winter rainfall as long as the soil
was well drained.
Thank you for the replies.
My searches on this, and the 2 replies I have had (1 off-group), suggest the
necessity of a cold winter dormancy. What should I do about the previous
year's foliage. The foliage I cut off was long (30-40cms) and floppy,
whereas the display plant when I bought mine last summer was much shorter
and in full flower. Does it flower on the current year's growth or the
previous years. I assumed, maybe wrongly, that I should treat it as a normal
herbaceous and cut it to the ground in late winter.
