Lorn's post about the traveling lilies got me think8ng. I have 6 pots of one new variety, three pots each of two other varieties....all new to me this spring. The six are Fusion. I dug down to the one that did not crown, and it is just slow. I has sprouted....and I replanted it. The other two are lankongeuse and Red Mildew Ball, all new bulbs from Hyde. They had done as Lorn suggested...grown to the end of the pot horizontally, and then grew downward, catching themselves on the bottom of the pot. I forced a top crowning for them and repacked the pots.
I would not have known to look without these posts.
