I have had the best luck with large, quality bulbs, but they do tend to be pricier. So experiment with what you have. Just be sure to buy bulbs that have no soft spots or mold on them. And remember to fertilize so you don't get all leaves.
I like to start mine for bloom after the holidays for a shot of color in January or February. Allow six to eight weeks. Some warmth helps them grow faster but a cool place later on will keep the bloom going longer.
So save some money and keep your favorites! Here are mine.
