I have Fireball for the first time, too, and I like it as well.
I'm thinking I will order cuttings of some pot mums soon, for sale in the late summer. I'll make a second order for my fall color mums. I was also looking at Argyrantheum, if anyone has ever grown that and can offer advice.
I've been window-shopping at the NC farms site:
