I planted a White "Lady Banks" last year and trained it on a trellis. It had no thorns or blooms the first year and I began to think it had been mismarked. Perhaps it wasn't a rose. Well, low and behold. . . It now has a few, very few thorns and the beginnings of a few buds. Is this normal to be so slow in producing? should I do anything else for it? The plant structure and leaves are very good. It looks very healthy.
