Oriental lilies grow from bulbs that produce an array of large, colourful flowers in the spring. Oriental, or Asian, lilies bloom earlier than many other members of the Lilium genus and are more durable than many other varieties.
Description and Types
Oriental lilies can grow as tall as 5 feet, according to Iowa State University. Dwarf hybrids grow to only 1 to 2 feet tall. Oriental lily varieties include Alpenglow, Apollo, Connecticut King, Enchantment, Grand Cru, Jet fire, Latoya and Luxor.
Oriental lilies do best in well-drained, slightly acidic garden soil. They also can be grown in pots, especially the dwarf varieties. Plant Oriental lily bulbs in the fall at a depth of about 6 inches. Most types of this plant need full sun and respond well to a 3- to 4-inch layer of mulch in their growing area.
Planting Distance for Bulbs
The Lily Garden recommends leaving at least 6 inches of "elbow room" for each Oriental lily bulb. When planting several varieties, plant the bulbs of taller types toward the back of the flowerbed. Leave a radius of at least 6 inches around each bulb.
