General Culture: Click for monthly care information.
Easily grown in average, medium, well-drained soil in full sun to part shade. Prefers rich, organic soils. Best with upper plant in full sun and roots in shade. Mulch around plants to keep root zone cool. Plant bulbs 4-6" deep in fall or very early spring (some nurseries only ship bulbs in fall, however). Potted plants may be planted any time from spring to fall. Plant in groups of three for best display and space 12" apart. Bulbs need good moisture year-round. Do not allow soil to dry out. Remove flowers as they fade to prevent seed from setting. After bloom, cut plants back only after leaves and stems turn yellow.
Noteworthy Characteristics:
Oriental hybrid lilies are known for their intense fragrances, large flowers (6-8" wide) with recurved petals, and rich colors. 'Casa Blanca' is a popular Oriental hybrid cultivar that features pure white flowers (to 8-10" wide) with contrasting reddish-brown anthers. Blooms in mid-summer on rigid stems rising 3-4' tall. Flowers are very fragrant. Excellent fresh cut flower.
Problems:
For the average gardener, Oriental hybrid lilies are easy to grow. Usually pest free, but potential diseases include: (1) lily mosaic virus (prompt control of aphids which vector the disease is highly recommended, since there is no cure once infection occurs); (2) bulb rot (particularly in wet, poorly-drained soils); and (3) botrytis. Plants may need staking if grown in too much shade (stems weaken) or in locations exposed to strong winds.
Uses:
An excellent, showy flower that provides color and contrast to the summer perennial border. Plant in groups near the patio and enjoy the fragrance when sitting outside on summer evenings. Also may be grown in pots or containers, but plants and flowers will be somewhat smaller.
