Culture
Easily grown in average, medium, well-drained soil in full sun to part shade. Prefers rich, organic soils. More drought tolerant than many other types of lilies. Bulbs prefer good moisture year-round, however. Plant bulbs 6-8" deep (slightly less in heavy clay) and space 18-24" apart in either fall or early spring. Plant in groups of at least three bulbs for best display. In optimum growing conditions, each bulb will multiply over time to form a large clump of stems. Mulch around plants to keep root zone cool. Protect from wind. Although stems are strong, staking for this tall lily is advisable. Remove flowers as they fade to prevent plant energies from being wasted on seed production. After bloom, cut plants to the ground only after leaves and stems have turned yellow.
Noteworthy Characteristics
Regal lily is a trumpet lily which typically grows 4-5' tall (sometimes to 6' when well established) on rigid stems. 'Album' features large, outward-facing, fragrant, white trumpets (6-8" long). Flowers bloom in early to mid-summer. Each stem typically carries up to 25 flowers. Long-lasting fresh cut flower.
Problems
No serious insect or disease problems. Some susceptibility to: (1) lily mosaic virus (prompt control of aphid populations which vector the disease is recommended since there is no cure once infection occurs), (2) bulb rot (avoid wet, poorly drained soils) and (3) botrytis. Taller plants may need staking.
Garden Uses
Excellent showy flower for the summer border or cottage garden. Group near a patio where the fragrance can be enjoyed on a hot summer evening.
