You don't need a garden or a green thumb to bring the bright yellows and oranges of spring flowers into your home. At any time of year, you can grow cheerful, sturdy daffodils (Amaryllidaceae) in glass pots or bowls with nothing more than a handful of pebbles and some water.
Chill daffodil bulbs in a cold, dark space for approximately four months before the desired planting time; keep them at a temperature of 35 F to 45 F. The cold temperatures trigger a biochemical response in the bulb that spurs the flower to begin developing. Remove the bulbs from cold storage for planting.
Wash and dry a wide glass vase or a wide, shallow glass bowl. Place clean pebbles in the bottom to a height of 2 to 3 inches.
Gently press large, healthy daffodil bulbs down into the pebbles. The large, bottom half of each bulb should be completely anchored in the pebbles, with the smaller, sprout end pointed upward and above the pebbles. Plant as many bulbs in the container as it can accommodate.
Pour cold water carefully into the pebbles in the container, no higher than the bottom of the bulbs. Add water as needed to maintain the water level. Keep the pots at room temperature. Place them in indirect lighting for the first two weeks, then move the pots to a bright window where they will receive full sun.
