Hi there. I haven't been around much lately, but today found this really beautiful flower by the side of the road. Actually, a lot of them. They had recently been slashed back so the house on the other side could have a better view of the river! Anyway, I found quite a large patch and I brought a few plants back home with me, that had been almost buried by dead gingers and heliconia stems. I think it is a gesneriad, possibly a Kohleria species. Sorry I'm not giving much info, but hoping someone may just recognize the plant from the flower and leaves.

Here is the flower. It is tubular, about 1" long with the petals flaring out to about 1/2".
