Evan, those look good to me, is it that they haven't bloomed well that's making you think they aren't happy? After they bloom here the weather often gets hot and humid, and the bloom stalks will start browning and looking nasty, so I typically cut them off. In one bed the blooms are too tall, and I snap them off before they form. I've been finding seedlings all over the place, even in the lawn, so I'm trying to stay on top of the dead heading anyway. I've grown them for years, but have never had them self seed as freely as they do here.
