There doesn't seem to be a way to send you an email through Gardenweb. You won't get many responses because many of us don't want to put our addresses and personal information on the thread for everyone to see. If you go to my page and send me an email with your address I'll send you some seeds. Feel free to check my list to see if there's anything specific you want. I am in Nebraska zone 4/5.We have hot summers, too. I have quite a few flowers that butterflies like and I'm as addicted to saving seeds as I am to growing flowers. I'm not looking for a trade--I have more than enough seeds. Love to share with others. Heidi

OK, then why post it here? I just don't understand why you did this.

Around my natural pond I have bee balm in several colors and the hummers are all over it. Same with lobelias. The hummers arrive when the bog irises start blooming and stay to frost. Jewel weed is a favorite but it throws it seed everywhere. At least the extras pull out easy or are controled easily with a lawn mower. Never tried a floating island so I don't know how they'd do on one. Impatients take a lot of sun when they are consistently wet. My pond is spring fed and tends to be a little cold for them.

I'm glad you posted this question. I have my plants scattered around in different places in the yard and I was thinking about making a single hummingbird garden instead. It didn't occur to me that the hummingbirds might not like it that way. I was just thinking that it would make it easier to VIEW the hummingbirds. I feel like when I go over to watch them in one area, they just fly off to another. I have only Ruby-throat hummingbirds here. I wonder if some species are more territorial than others.
