I bought these sunflowers that only get about 12 inches. It says annuals, and I was wondering if I can keep them inside during the winter. Will they keep or will they flower? I have windows that are 8 ft by 6 ft, sunny in the afternoon till sun down. I’m new to flowering, but these are so pretty. Wishing I can keep them inside. Also, do I cut the old flowers off or leave them?

With sunflowers, them bloom once and then die. Even if you bring them inside, they will not live. You can however plant new seeds that you can try growing over the winter indoors.
You do not have to remove the spent blooms. Once the plant flowers, removing the blooms will not result in new blooms (which does happen with some other plants). Many people like to leave sunflower heads on teh plant so that the birds can eat the seeds in the winter. But you can cut them off and harvest the seeds so that you can grow more in the future.
