Celosia is a tender plant that is usually considered an annual but if you can keep it under greenhouse conditions, it will grow as a perennial. They need about 8 hours of sunshine a day, which you should be able to provide in a greenhouse. They will flower at 70-75F. If your greenhouse is cooler than that you can still grow them, but they won't flower as freely. Enjoy your plants!

Will they flower normally after putting them out in the spring?
