It looks as if there are one or two offshoots of the original bulb that are trying to send up leaves and possibly one or two flower scapes. You can't leave them outside to freeze. Try bringing the pot inside and growing it as a houseplant. The big bulb probably won't flower at Xmas, but it should flower in the spring. The bulbs may go into dormancy on their own, with a shorter day length, and the new growth may die back. Love to see what happens to the baby bulbs. Some Amaryllis cultivars form clumps very quickly. They want to put their energy into lots of bulblets. Some cultivars just make bigger bulbs without producing bulblets. Keep us updated on this.
