I planted seeds last year, read that they would only produce big leaves the first year, which they did. This year I am expecting them to flower, but it doesn't look like anything is producing yet. We didn't get a very cold winter this last year. Does that have something to do with it or should I just wait patiently and see what happens?
Optimize the growing conditions and avoid excess nitrogen fertilizer that can inhibit flowering.
You can also apply some phosphorous to encourage flowering.
Bone Meal is a good way to add phosphorous to the soil.
