Interesting looking plant and a lovely specimen
, but I have no idea what it is.
One thing that I do notice is that it appears to be a caudiciform, which are frequently used for bonsai. So your GF may not be as far out in left field as you think. Maybe
@Reine or
@LAGirl may have an ID of your plant. Seeing the bloom will also give a better indication of its identity. BTW,
jmtoni to NGA and the Houseplant forum. We're glad to have you with us. Others will respond to your thread soon.
