Allium Schubertii bulbs do multiply over time. This is one of the wonderful characteristics of this particular variety of allium. As with other ornamental onions, allium Schubertii bulbs are typically planted in the fall. This timing allows them to experience a cold-chilling period that is necessary for them to bloom successfully in the following spring or summer.
When planting allium Schubertii bulbs, it is important to choose a location that receives full sun or at least six hours of direct sunlight per day. These bulbs prefer well-draining soil, so adding organic matter or compost to the planting area can help improve the drainage if needed. It’s also a good idea to incorporate some bone meal or bulb fertilizer into the soil to provide the necessary nutrients for healthy growth.
Once planted, allium Schubertii bulbs will establish themselves and produce their stunning globe-shaped flowerheads. These flowerheads consist of numerous individual star-shaped flowers that create a visually striking display. As the flowers fade and the plant matures, it will begin to produce offsets or bulblets. These are essentially small bulbs that develop alongside the main bulb.
Over time, these offsets will continue to grow and multiply, eventually forming a cluster of bulbs. This natural process of multiplication can result in a larger and more robust display of allium Schubertii in subsequent years. It’s important to note that this process can take several years, so patience is key when it comes to seeing an increase in the number of bulbs.
To propagate allium Schubertii, you can carefully dig up the bulbs in late summer or early fall when they are dormant. Separate the offsets from the main bulb, taking care not to damage the roots or bulbs. Replant the offsets in a new location or share them with fellow gardening enthusiasts. It’s worth mentioning that allium Schubertii may not bloom in the first year after being transplanted, as they may need time to establish themselves in their new location.
Allium Schubertii bulbs do indeed multiply over time. This ability to multiply and produce offsets is one of the factors that make them a popular choice among gardeners. With proper care and patience, you can enjoy an ever-increasing display of these stunning flowering onions in your garden.
