i'm not sure if cochleata really has a scent usually...? i've found no mention of it being fragrant, and a few saying it is not. but green hornet is noted to be fragrant... this one is most fragrant in bright light. only a residual scent in the evening. all the pictures i find of cochleata and the one i had years ago had larger plants and larger flowers. also darker, curly flowers. i hear of a dwarf form of cochleata, but i cannot find pictures, but i'm still guessing this to be a hybrid.
