Those are just cheap, off the rack glads bought in bulk packs. Buy the assorted mix for the best surprises. Lowe's had unusually large, solid corms but they are stocked early so I bought them and kept them in my garage until early May. They become well picked over if you wait until about time to plant them. I haven't tried it but I have read where you can plant a group of them separated by about two weeks repeated several times and have a nice flower garden for a couple of months.
