The “Stargazer Orchid” is a common misnomer for the Stargazer Lily, Lilium ‘Stargazer’. This confusion often arises due to the lily’s exotic, dramatic appearance and its widespread popularity as a cut flower, leading many to associate its striking beauty with the allure of orchids. This article provides guidance on cultivating the Stargazer Lily.
Understanding the Stargazer Lily
The Stargazer Lily (Lilium orientalis ‘Stargazer’) is a hybrid plant within the Oriental lily group. It was specifically bred in the late 1970s by Leslie Woodriff to feature distinctive upward-facing flowers, which gives it its celestial name. These large, star-shaped blossoms boast a vibrant palette, typically displaying deep pink to red petals with crisp white edges and a scattering of dark speckles towards the center.
Beyond its visual appeal, the Stargazer Lily is celebrated for its intense, sweet, and often spicy fragrance, which can fill a garden or indoor space. Its dramatic flair and potent aroma contribute to its popularity in floral arrangements and gardens, where its robust stems often support multiple blooms.
Stargazer Lily Care Essentials
Light
Stargazer Lilies flourish in locations that receive ample sunlight. They perform best with at least six hours of direct sun exposure daily, ideally concentrating on morning light. While they can tolerate partial shade, insufficient light may result in leggy stems and reduced blooming.
Watering
Consistent moisture is important for Stargazer Lilies, but they do not tolerate waterlogged conditions. The soil should remain evenly moist, especially during the active growing season. Proper drainage is important to prevent bulb rot, so avoid allowing water to stand around the bulbs. Mulching around the base of the plants can help retain soil moisture and keep the roots cool.
Soil
These lilies prefer well-draining soil that is rich in organic matter. An ideal soil pH for Stargazer Lilies ranges from slightly acidic to neutral. Clay soils should be amended with compost or other organic materials to improve drainage and fertility.
Temperature and Humidity
Stargazer Lilies are hardy in USDA Zones 3-9. They generally thrive in warm conditions, with optimal bloom production occurring in mid-summer when temperatures consistently reach 80 to 90 degrees Fahrenheit. While the flowers and foliage enjoy full sun, the bulbs prefer cooler soil, which can be achieved through mulching.
Fertilizing
Stargazer Lilies are considered heavy feeders due to their large, showy blooms. Applying a balanced 10-10-10 fertilizer in early spring as new shoots emerge is beneficial. Supplemental feedings throughout the growing season can also support vigorous growth and flowering. For soils that are more alkaline, an acid-forming fertilizer can help them thrive.
Planting and Cultivation
Stargazer Lily bulbs can be planted in either the fall or early spring, with fall planting allowing for better root establishment. When selecting a site, choose a location with well-drained soil and adequate sunlight to encourage robust growth and abundant blooms. These lilies perform well in garden beds or containers.
For ground planting, bulbs should be placed approximately 6 to 8 inches deep and spaced 8 to 12 inches apart. If growing in containers, select pots at least 6 inches wide with drainage holes, using a potting mix rich in organic material. While Stargazer Lilies generally possess sturdy stems, taller varieties or those in shaded locations might benefit from staking to provide additional support.
Troubleshooting Common Problems
Pests
Aphids are common, often appearing as small insects that cluster on new growth and can cause yellowing or curling of leaves. A strong spray of water can dislodge minor infestations, while insecticidal soap or neem oil can address larger populations. Lily leaf beetles, identifiable by their scarlet shells, can also feed on leaves, stems, and flower buds; neem oil applications can help control them.
Diseases
Fungal issues like botrytis blight are common diseases affecting lilies. This can manifest as brown or gray spots on foliage and can cause flower buds to rot. Ensuring good air circulation around plants and avoiding overhead watering can help prevent fungal growth. Removing and destroying the infected plant parts can help prevent spread.
Lack of Blooms
If a Stargazer Lily fails to bloom, insufficient sunlight is a common cause, as these plants require at least six hours of direct sun for optimal flowering. Improper planting depth can also hinder blooming. Nutrient deficiencies can also impact flower production; consistent fertilization throughout the growing season can help address this.
Yellowing Leaves
Yellowing leaves on Stargazer Lilies can indicate underlying issues. Overwatering is a frequent culprit, as soggy soil can lead to root rot and nutrient uptake problems. Conversely, severe underwatering can also cause leaves to yellow and wilt. Nutrient deficiencies, particularly nitrogen, may also result in yellowing foliage, which appropriate fertilization can correct.
