Dainty beauty

Bit of a rush today so snapped this beautiful little plant - I have a feeling I've Blipped it before, but never mind.

It's Sarmienta repens, a small rambling semi-climber from Chile in the family Gesneriaceae. I have tried it outside but lost it - it's probably a bit fussy and likes a moist spot. This one's in a pot in the cold greenhouse - the flowers are only an inch long.
