Some years I see lots of seed set on my venerable (>20 year old) Sinningia leucotricha, some years none. In the greenhouse, outdoors, doesn't matter. This year the old plant is spending the spring in the greenouse a couple of feet away from fan that is running all the time to keep the air circulating. I happened to notice today that literally every flower had produced a fat seed pod. A couple of other plants, seedlings from the older one, were barren. They were just outside of the bulk of the air flow from the fan. Is it common for sinningias to be wind pollinated, or was my fan just acting like a giant bee? And who was it that said Sinningia leucotricha was hardy? Do I dare try one outside? --Roy NW of Boston
