Don’t see why not what sort of amaryllis are they? They will properly form into bulbs and may not be flowering size for a few years.

About 3-5 years from seed to bloom for Dutch Amaryllis, and about 5-7 years for Amaryllis belladonna. Rewarding, but definitely not instant gratification. Plant the seeds about 1/2 inch down, in a pot of fast draining soil mix--now for Dutch Amaryllis, or in the fall for Amaryllis belladonna. The new seedlings look like coarse grass, and will have marble-sized bulbs by the beginning of next growing season, when they can be transplanted into the ground, or individual pots.
