we have nearly 200 mature lily bulbs of just about every variety in our yard. hence, we end up with hundreds of these little bulblets every fall when we divide. we don't save all of them, but we do save the bigger ones. we have two very large cedar boxes that these bulblets go into for a year or two until they become big enough to be considered, "mature". then we either keep them for our yard or simply give them away. takes a few years to get to that point, but if you do it every year and rotate your stock, you will have a constant supply!
