My lankongense hybrids have always come up short (if they come up at all). Then usually if they came up the first year they are gone the second year. I have wasted too much money on those beauties!
They seem to grow very well for some people. I think my problem is too much rain all fall, winter and spring and heavy clay soil that drains very slowly. They dislike too much moisture. For me they may have done better in containers that I could pull under the eaves, but basically I have given up on them. Too many other good choices out there to fill up the real estate.
Another lily that requires perfect drainage is auratum and its hybrids. I won't buy those anymore either. Cherbourg lasted but one season for me. Any of those yellow orientals are off my list.
