Mine came from a vendor in Florida. They said to totally withhold all water. Why not give it a try? What have you got to lose but one season's growth? I keep mine in south window, only because that is its home. No other reason. I don't need keikis, I want flowers.
I finally went and bought a blooming size anosmum from Oak Hill lol....can't help it. I thought it looks much bigger but it looks pretty small and fragile, the stalk is about pencil-thick. I don't know if it's gonna die if I don't water them at all for 3 months lol.... I'm a little scare.
