I'd be hesitant to give your friend drugs, But who knows? Based upon my abuse of plants, crinums might work. Don't know if the should, but mine are outside in pots - very large pots - and went thru an unusually cold winter here with ice and snow. I have the Ellen B's and they are so gorgeous.
Drdawg - don't most hosts go dormant in the winter?
Brain drain time. Will come back if brain does.
