Kits of Amaryllis are available in garden centers and should be started five to six weeks before the holidays to have them ready for holiday time.
Plant one giant bulb in a container that is at least 6" wide or, for a fuller, more colorful display, plant three bulbs together in a 12" pot. The top third of the bulb should show above the soil.
Water thoroughly when planted and keep in a warm room in bright, indirect light.
Keep the soil moist throughout it's bloom cycle of two to three weeks.
They may be planted in the garden in the spring and brought in again in the fall.
