Crown Imperial Fritillaria imperialis 'Argenteovariegata' (v)
ABOUT
The plant known as Crown Imperial 'Argenteovariegata' is a striking and ornamental flowering plant that stands out in any garden setting. It is characterized by a unique and bold structure with a tuft of bright green leaves that crown the top of the stem, much like a pineapple top. Below this topknot of foliage dangle large, pendulous bell-shaped flowers. The flowers themselves are a vibrant orange or red color, which makes them particularly eye-catching against the lush greenery. Additionally, the foliage has a variegated pattern—the 'Argenteovariegata' part of its name signifies the creamy white to pale yellow streaks or edges on the leaves, adding a decorative contrast and enhancing the overall appeal of the plant. The leaves are lance-shaped and glossy, arranged in a spiral formation along the stem, contributing to the exotic appearance. The flowers emit a distinct scent that can be quite strong and musky, often described as fox-like, which is noticeable especially when standing close to the plant. This combination of bright coloration, intricate variegation, and unique architecture makes the Crown Imperial 'Argenteovariegata' a prominent feature wherever it is planted.

WaterThe Crown Imperial requires careful watering to maintain consistent moisture without waterlogging. Water the plant with approximately 1 inch of water once a week, adjusting for rainfall. During the growing season, this equates to about 0.6 gallons for a small garden area housing the plant. It's particularly important to keep the soil evenly moist during the spring and early summer when the plant is actively growing. Reduce watering after the foliage begins to yellow and die back, signaling the onset of the plant's dormant period.
LightThe Crown Imperial thrives best in full sunlight conditions, though it can tolerate a bit of partial shade. Choose a spot that receives at least 6 hours of direct sunlight daily to ensure the plant's health and optimal blooming. Avoid deeply shaded areas, as insufficient light can lead to weak stems and poor flowering.
TemperatureThe Crown Imperial prefers temperate climates, with an ideal growing temperature range between 50°F and 70°F. It can survive minimum winter temperatures down to 5°F. To encourage vigorous growth and flowering, protect the plant from extreme heat and cold, ensuring it is not exposed to temperatures above 80°F for prolonged periods.
PruningPruning the Crown Imperial involves removing spent flowers after blooming to prevent seed formation, as it can weaken the plant. Cut back the foliage only after it has yellowed and died down in late spring or early summer. Pruning is typically only required once per year, after the plant has finished its flowering cycle, to tidy the plant and conserve its energy.
CleaningAs needed
SoilThe Crown Imperial or Fritillaria imperialis 'Argenteovariegata' thrives in well-draining soil with a generous addition of organic matter, such as compost. The ideal soil pH should be neutral to slightly acidic, ranging from 6.0 to 7.0. A mix of two parts loam, one part peat or leaf mold, and one part sharp sand or perlite creates the optimal conditions for growth.
RepottingCrown Imperials generally do not need to be repotted frequently. Repotting should be done every three to five years or when the bulbs outgrow their container. It's best to repot them after the foliage has died back post-blooming season.
Humidity & MistingCrown Imperials prefer moderate humidity levels around 40-50%. Avoid overly dry air, but also protect the plant from excessive humidity which can encourage bulb rot.
Suitable locationsIndoor
Ensure bright light, cool temps, and moderate humidity.
Outdoor

Life cycleCrown Imperial 'Argenteovariegata' begins its life as a bulb, planted in the late summer or fall, which overwinters in the ground. In early spring, the bulb sends up a sturdy stem topped with a tuft of lance-shaped, variegated leaves. As the stem grows, a whorl of bell-shaped flowers, typically orange, red, or yellow, with a marbled variegation on the foliage, develops beneath the leafy crown, blooming from mid to late spring. After flowering, the plant goes into a period of photosynthesis to replenish the bulb's energy stores. By mid-summer, the foliage yellows and dies back as the plant enters dormancy, retreating into the bulb below the soil surface. The cycle repeats the following spring when temperatures rise, and growth conditions are favorable.
PropogationPropogation time
Spring to Summer
The Crown Imperial, known by its botanical name Fritillaria imperialis 'Argenteovariegata', has a propagation period that is most successful in the late summer to autumn months. The most popular method of propagation for this plant is by bulb offsets. These offsets are essentially small bulbs that form at the base of the parent bulb. Once the foliage of the plant has died back after flowering and the bulbs have begun their dormancy period, gardeners can gently lift the plant from the soil. They will find small bulb offsets clinging to the larger, parent bulb. These should be carefully separated and can be replanted immediately. The offspring bulbs should be planted at a depth around three times their height, in well-drained soil and in a location that receives full sun to partial shade.
