My neighbour kindly gave me some tubers of this very exotic lily. I planted mine at the same time as her with fresh soil and plenty of water. They came up much more slowly than those of my neighbours, and didn’t flower. This is a picture of the gorgeous flowers on the neighbouring plant!
The only difference between our two plants was that hers were planted in a terracotta pot whilst mine were encased in a large plastic one. All other things being equal, I will be going with terracotta next year.
