I have OrienPet lilies (love them the scent and height) here for years they do well here our snow cover is not consistent, I wonder if the soil is also a factor in growing them. I planted Conc d'Or last year so will see how that one does this year.
If you want to be happy for a lifetime plant a garden!
Faith is the postage stamp on our prayers!
