I got some of the dwarf ones from Lowe's last year. They were only about 18in tall, so not the problem with blowing over that Jonna mentioned.
Just noticed they are coming up again, and after chatting with you all about it, think I will try some of them in my little pond this year. I've had them beside the pond before, but had to remember to water them. They have really pretty flowers, some are white with faint pink spotting, and some are yellow with the same pink mottling. Let's see if I can dig back and find a pic.
