Have you looked at Fractal's comments about Peruvian Lillies Linda. As GJ said of one of our polymath friends ' he knows what the Incas have for breakfast' (see below)

I have only ever got foliage and after 4 years and last winter they have given up the ghost. So I was bitterly dissapointed with them.

I have about twenty bulbs in a pot. The leaf is great, just no flowers. The friend who gave them to me has been growing them in Glasgow for the last twenty-five years. She had no flowers either. We have decided it was the awful July we had, too much rain.

I have several clumps of hemerocallis in my garden and I divide some of them each year to sell from my plant nursery. About half of those I divide flower that year almost all of the rest the following year. I don't feed them at all but they are in good light soil in a sunny spot and I'm in North Cambridgeshire so it may be your climate that is causing the difficulties.
