I've always found the flowers endearing...they sort of remind me of cute little dutch clogs
I would have said that they didn't have a smell... but pressed by your question, abax, I unfortunately discovered, that they have one... but you have to stick your nose right next to the flowers, before you discover the very faint odour of "what dogs leave in the streets" - thank god, you wouldn't notice unless you try really hard! I don't know for sure, but guess that the plant is fly polinated.
Yours is very beautiful and very solid red. Looks very healthy as well. I love mine, and it grows like a weed!!! Only flowers for me though if it gets at least a couple hrs of direct warm sun. I grow mine in straight sphagnum moss in a wooden basket.
