Some lilies (e.g. N. American tiger lilies) produce bulbils in the leaf axils. You can take them off and grow them on but they'll take a few years to get to flowering size.

correct again beattie. My L pardalinum also produces bulbils. plants for free but as you correctly say they take many years to get to flowering size.

:-) Thanks SBG! I've never had the patience to get them to flower.

Thanks SBG and Beattie I dont think I will be planting and waiting

Why not, Steve? They only take a few years to flowering size bulbs. A year less than seeds, in my experience, and an excellent way of bulking up stock.
Another benefit, over growing from seed, is that these bulbils will produce the same lily as the original if it is from a cultivar.

You could just pop some in a corner and forget about them - nothing to lose!

I put them in a 3litre pot and left them behind the compost bins. they are nice plump bulbs. hoping for flowers next year.
