When I established my terrarium several months ago I bought a bunch of different things from a bunch of different places. Black Jungle was selling Sinningia tubiflora, and the description sounded delightful! "One of the easier of all Gesneriads to grow, S. tubiflora does best on a sunny windowsill or outdoors in partial sun. Narrow grey-green leaves are paired along the stems that reach 8"-10" tall. From this arises 12" spikes carrying 2" long tubular white flowers that are quite fragrant, unusual for a Gesneriad!" Well whatever they sent me won't stop growing!! It has exceeded 36 inches in length and has completely outgrown my 24" deep(tall) terrarium. I'm super new to gesneriads, so I'm hoping someone else can tell me.... is there really a Sinningia that gets this tall?? My plant is definitely geophytic. The bulb/tuber is smaller than a tennis ball, roughly speaking. But is it a Gesneriad? I have no idea. It's not showing any signs of blooming. I'll try to send a picture this weekend.
