WaterOrnamental onions, including the 'Early Emperor', should be watered thoroughly to establish their root systems after planting, but once established, they require minimal watering due to their drought-tolerant nature. During the growing season, a good soak every couple of weeks should suffice, providing about 1 inch of water each time. It's essential to ensure that the soil drains well, as ornamental onions do not like soggy conditions. Watering in the morning is ideal, as it allows the foliage to dry out during the day, which can help prevent disease.
LightOrnamental onions like 'Early Emperor' thrive in full sun, which means they need at least 6 hours of direct sunlight each day. The best spot for these plants is a location where they receive unfiltered sunlight throughout the day. Avoid planting them in areas that are shaded or partially shaded, as this will affect their blooming and overall health.
TemperatureOrnamental onions, such as 'Early Emperor', are hardy and can tolerate a range of temperatures. They can survive temperatures as low as 20 degrees Fahrenheit and as high as 90 degrees Fahrenheit. The ideal temperature for optimal growth is between 55 and 75 degrees Fahrenheit. These temperature ranges allow the 'Early Emperor' to grow robustly and bloom well.
PruningPruning is not typically necessary for ornamental onions like 'Early Emperor'. However, after blooming, it's beneficial to remove the spent flower heads to prevent self-seeding and to tidy up the plant. Generally, it's best to prune ornamental onions after the flower heads have dried out, usually in late summer or early fall. Regular removal of damaged or yellowing leaves can also be done as needed.

Life cycleThe life of 'Early Emperor' ornamental onion begins with seed germination, which occurs in late winter or early spring as the soil warms up. Seedlings establish a basal rosette of foliage, and the plant begins to develop its root system. As temperatures rise, it enters the vegetative growth phase, where leaves elongate and gain strength. In late spring to early summer, 'Early Emperor' reaches the reproductive stage, producing tall scapes topped with large, spherical purple flower clusters that attract pollinators. After flowering, it sets seed and, if conditions permit, the plant will self-sow. Finally, as the season progresses towards fall, the foliage dies back and the plant enters dormancy, surviving underground as a bulb until the next growth cycle begins.
PropogationPropogation time
Spring to Summer
The most popular method for propagating Allium jesdianum 'Early Emperor', often referred to simply as ornamental onion, is through division of the bulbs. Typically, this is best done in the fall, after the leaves have died back but the soil is still warm. To propagate, carefully dig up the clumps of bulbs and gently separate them by hand, ensuring that each division has a portion of the basal plate and some roots attached. Replant the bulbs immediately at a depth approximately three times the height of the bulb, which is typically 3 to 4 inches (7.6 to 10.2 centimeters), and spaced about 6 to 8 inches apart. The newly planted bulbs will then establish roots before the onset of winter, leading to new growth in the spring.
