I don't save many seeds anymore, and I don't honestly know if I have any hummer seeds to trade. I might have some older ones in my seed box, but probably won't be in "seed mode" and go through that box until after Christmas. I'm in holiday mode now.
My hummers seem mostly attracted to salvias (annual and perennial), penstemon, lobelia cardinalis, nicotiana. But they're not picky eaters. I get a lot of them and they visit almost every flower, including zinnias, impatiens, butterfly bush, and petunias. Sometimes it seems it depends on the actual cultivar, though. Nicotiana has always been a big attractor for me, but I've tried a few of the dwarf variety (which had no fragrance) and the hummers totally ignored them, so maybe fragrance matters. But if anyone knows of a fragrant nicotiana 1 to 2 feet tall, please tell!
