Hey, I've never planted one in AZ. I know we've discussed this before... maybe long ago. I did have crinum in Los Altos, CA. A long border of pink. They disappeared half the year and came back strong every season. Can't remember the cycle. Summer bloom? Didn't receive water except when I watered the dichondra lawn. They were planted at the top of a retired riverbed. Fertile. Sure pretty.
How is it doing in this heat? How did you end up planting it? Container?
