Stargazer lilies make a bold statement in any garden. These hardy perennials thrive in USDA Hardiness Zones 4 to 8 and prefer full sun to partial shade. Growing to a height of 3 to 5 feet, the stargazer blooms in midsummer. Blooms range in color from white and pink to red with the spectacular pink bloom being the most common. These highly fragrant lilies bloom atop a tall slender stem that holds six to nine blooms that open gradually over two weeks. Blooms often reach 8 inches in diameter making them a stunning cut flower.
Prepare the planting site in an area that receives six to eight hours of direct sunlight a day. Till the soil to a depth of 8 to 10 inches. Remove rocks, roots or other debris. Mix in 2 to 3 inches of compost or well-rotted manure to improve drainage and aeration.
Dig under the roots of the stargazer with a spade or garden fork. Bulbs may be deeper than expected as the roots can pull the bulb lower into the soil as it grows. Use care not to nick or cut the bulb. Lift the bulb free of the soil and shake gently to remove excess soil.
Dig a hole in the prepared bed deep enough to plant the bulb so the top of the bulb rests 6 inches below the soil. Spread roots and settle the bulb in the soil. Cover the bulb with soil and firm down to remove air pockets. Water deeply to moisten the soil at the root level.
Mulch newly planted stargazer lilies with 2 to 3 inches of leaves or other organic mulch in late fall to protect the bulbs from the effects of freezing and thawing during the winter.
