A daffodil bulb will divide and redivide endlessly. That's why, like the peony, it is one of the few flowers you can find around abandoned farmhouses, still blooming and increasing in numbers fifty years after the farmer and his wife have moved to heaven, or the other place, Boca Raton. If you dig up a clump when no one is nearby and there is no danger of being shot, you'll find that there are scores of little bulbs in each clump, the progeny of a dozen or so planted by the farmer's wife in 1942. If you take these home, separate them, and plant them in your own yard, within a couple of years, you'll have a hundred daffodils for the mere price of a trespassing fine or imprisonment or both. I had this adventure once, and I consider it one of the great cheap thrills of my gardening career. I am not advocating trespassing, especially on my property, but there is no law against having a shovel in the trunk of your car.
