The Stargazer Lily (Lilium ‘Stargazer’) is a popular and intensely fragrant hybrid developed from the Oriental lily group. Its flowers are defined by deep pink or crimson coloration, often speckled with darker freckles, set against crisp white edges. This appearance and spicy aroma have made it a favorite choice for both home gardeners and the commercial cut flower trade. The cultivar is notable for its large, upward-facing blooms, a trait that inspired its name.
The Natural Outdoor Blooming Season
The Stargazer lily’s natural peak season occurs during the warmest part of the year in temperate climates. These perennials require winter dormancy to replenish energy before sending up new growth. Consequently, bloom time in the garden is restricted to mid-to-late summer.
The specific month for flowering shifts based on local climate and the garden’s USDA hardiness zone (typically zones 3 to 9). Gardeners in warmer regions might see blooms as early as late June, while those in northern areas often experience the peak in July and August. The plant produces a single flush of flowers annually, which lasts for several weeks.
Year-Round Availability in the Florist Trade
Despite its limited outdoor season, the Stargazer lily is available to florists and consumers throughout the year. This consistent supply is managed through controlled agricultural environments and global sourcing. Commercial growers utilize greenhouses to manipulate the lily’s growth cycle, forcing the bulbs to bloom outside of their natural summer schedule.
This process involves subjecting the bulbs to a controlled cold period, often lasting about twelve weeks, to mimic winter dormancy. After chilling, the bulbs are planted in a greenhouse where light, temperature, and moisture are regulated to induce flowering approximately 90 days later. When domestic production is low, wholesalers import Stargazer lilies from countries with reversed seasons, such as the Southern Hemisphere, or from major producers like Holland, Ecuador, and Colombia. This international network ensures the cut flower remains accessible even during winter.
Timing the Planting Cycle for Home Gardens
For the home gardener, successful flowering depends on the precise timing of planting the bulb. The optimal window for planting Stargazer lily bulbs is either in the late fall or early spring. Fall planting is ideal because it allows the bulb several weeks to establish a robust root system before the ground freezes and the plant enters winter dormancy.
When planting, the bulbs should be placed in well-drained soil at a depth of six to eight inches. The location must receive at least six hours of direct sunlight each day. The plant benefits from having its roots kept cool, which can be achieved with a layer of mulch. Bulbs planted in the fall will emerge in spring and mature to flower that same summer, reaching the mid-to-late summer bloom period.
