Hi Arnold, I grow this plant successfully in Berkeley, but even our autumn heat here (yes, it's warmest from September to October here) where daytime temperature can get to 90F can cause the plant to go dormant. The trick is to keep it from getting too hot or too cold because it will go dormant under those conditions. In your area, I suggest you grow it as a winter grower where night time temp is min 45F but daytime temp should be in the high 50's or 60's otherwise the tubers won't break dormancy. When it's in dormancy, keep it dry-ish and somewhere nice and cool.
