Botanical Name: Narcissus spp.
Growing daffodils indoors will bring a bright bouquet of spring-fresh flowers to your home in the middle of winter.
Naturally spring-bloomers, daffodils are easy to force into bloom early. Making a plant bloom at a time other than its natural bloom time is called "forcing." Start forcing daffodils sometime in October or November for mid-winter to early-spring flowers.
You have beautiful daffodil varieties to choose from -- in shades of yellow, cream, orange, pink or white. The trumpet, also called a cup, may be a color contrasting to the ring of petals. Sizes vary quite a bit, from pint-sized minis to tall plants with giant flowers.
As if daffodils aren't showy enough, some of them flaunt double petals, frilly trumpets -- even 2 colors per bloom.
Choose bulbs for forcing. Some common varieties that are good for forcing are listed below. Some large flower heads get pretty heavy and will need to be staked.
Miniature varieties are ideal for growing indoors. Don't dismiss miniature daffodils -- they're charming planted close together in a pot.
Because daffodil varieties tend to bloom at different times, it's best not to mix them. They tend to look best, anyway, in a mass planting of 1 variety per pot.
There are several cultivars available that are especially dependable for forcing.
Daffodils with bright yellow blooms include 'Dutch Master' ...'Soleil d'Or'...and 'Unsurpassable'.
Bi-color daffodils include 'Barrett Browning', a long-time favorite with snowy white petals and an orange-red trumpet. 'Fortune' has soft-yellow petals with a trumpet edged in dark orange. 'Ice Follies' is white with a creamy yellow trumpet.
Miniature daffodils only reach about 6 in (15 cm) tall and include 'Little Gem', 'February Gold' and 'Tete-a-Tete'.
Double-bloom varieties include buttery-yellow 'Bridal Crown' and pink-and-white 'Repleat'.
The only difficult thing about growing daffodils may be choosing a variety.
When in full bloom, keep potted daffodils in a bright location out of direct sun. Make your daffodils last longer by keeping the pot in a cool room. Flowers will last about a month if kept at a maximum of 60°F/16°C.
Height: Up to 18 in (46 cm); miniature varieties reach 6 in (15 cm).
Light: Bright indirect light. Rotate the pot once in a while because growing daffodils will tend to lean toward the light source.
Water: Keep soil lightly moist. Growing daffodils are thirsty, so it's a good idea to check the soil often.
Humidity: Average indoor (around 40-50% relative humidity). Indoor humidity can drop drastically during the winter months without our noticing it. It's a good idea to use a humidity gauge, rather than guess. The most efficient way to raise the humidity for your houseplant is with a cool-mist room humidifier.
Temperature: After the cold treatment (see "steps to forcing" above) keep cool 60°F/16°C while plants are in bloom.
Soil: Peat moss-based potting mix
Fertilizer: Feed every 2 weeks with a balanced water-soluble fertilizer diluted by half.
Propagation: Daffodil bulbs cannot be forced a second time indoors. You can transplant the bulbs outdoors, but it may take 2-3 years before they'll bloom again. If you want to keep them, allow the foliage to die back naturally, storing daffodil bulbs in a cool, dry place. Then plant the bulbs in your garden in the fall.
