Thanks all for the kind comments.
It does have a scent, but not like rootbeer (at least to me). It is more of a faint musky smell.
Jean, the individual flowers are about 7mm across.
I grow this warm to hot in summer (under 65% shade cloth and full shade in the afternoons). Water every other day. In winter it is down in the basement grow room with the other plants. Higher light and drier than in the summer (Watered every 3 or so days). Plant looks like hell, but seems to like the misery.
