Fill a shallow dish with clean pebbles or floral marbles. Use a dish that is deep enough to hold approximately a 2-inch layer of pebbles.
Set the bulbs in the pebbles with the flat side down. Push the bulbs into the pebbles just deep enough to hold them upright. Space bulbs approximately 1 inch apart in the dish.
Add water to the dish until the water just touches the bottom of the bulb. Set the dish in a cool, dark room until the stems begin to emerge.
Move the dish to a warm, sunny windowsill when stem growth begins. Replenish the water in the dish to maintain the level as it is used or evaporates.
