Introduce soft elegance and airy charm to your late spring garden with Multibulbosum Allium. This unique allium variety features creamy ivory flower heads with a delicate green eye, forming full, rounded globes that hover above the foliage on tall, slender stems. Each bloom cluster is made up of dozens of starry florets, giving the flower heads a light and lacy appearance that adds a refreshing brightness to garden beds.

Multibulbosum brings quiet sophistication to mixed plantings and pairs beautifully with bold-colored perennials or other allium varieties. It is ideal for naturalistic gardens, pollinator-friendly borders, and fresh or dried arrangements. Hardy, deer resistant, and easy to grow, this elegant allium returns year after year with minimal care, offering texture and contrast that softens and uplifts any planting scheme.

When & How To Plant

To plant allium bulbs effectively, timing and site selection are key. Aim to plant allium bulbs in the fall, ideally between late September and mid-November, once soil temperatures have dropped below 60°F (15°C). Choose a location that receives full sun and has well-drained soil, as alliums dislike excess moisture. Prepare the soil by loosening it to a depth of 8–12 inches and mix in compost or well-rotted manure to enrich it.

Plant allium bulbs 4–6 inches deep (depending on variety) and space them 6–8 inches apart, with the pointed end facing up. After planting, water thoroughly to help settle the soil and begin the rooting process. Apply a 2–3-inch layer of mulch to help retain moisture and insulate the bulbs through winter. As spring approaches and temperatures begin to rise, remove the mulch to allow new growth to emerge.

For those interested in enjoying alliums as cut flowers, harvest them just as the flower heads begin to open for the best vase life. Cut stems cleanly with sharp pruners and immediately place them in cool water. To prevent bacterial growth, strip off any foliage that would sit below the waterline. Display arrangements away from direct heat or sunlight, and change the water every two days. With proper care, alliums provide long-lasting, dramatic beauty both in the garden and in fresh floral displays.

Customer Testimonials

These bulbs are fabulous! Brilliant colours, sturdy stalks and the plant first season is full and leafy. Sometimes the first sprouting, the plants are a little scrawny, but these bulbs are well-sized with many flower stalks. The orange and yellows are vibrant, and the frilly edges are something I had not seen before.

It at be pre-mature giving this a five star review so early. I have never purchased this before so I have high hopes. I’m going off my last experience purchasing here before, timely shipment, and healthy looking plant.

JennChesapeake

This fall, I purchased a ridiculous amount of bulbs in hopes for an amazing spring presentation. Every year, I only order from Nagel Gladiolus Bulbs and it doesn’t disappoint. I also order for my mother’s yard as her Mother’s Day present. All the bulbs were healthy and nice.

JennChesapeake

These were the first to pop and bloom for me this year. Filled the yard with yellow sunshine and just pure JOY! They lasted just until the last two days of May this year and I honestly can't wait to order more for next year!

MercedesMN

I am a huge Nagel Gladiolus Bulbs fan. I’m quite embarrassed by the total transaction dollar amount I’ve spent here. When you find a good supplier, you stick with them. These bulbs are healthy, large, and ready to plant. I can wait to see what spring brings.

JennChesapeake

I ordered these along with some other bearded iris, and every single rhizome was healthy and had tiny green shoots when they arrived. I've never received bulbs or rhizomes from other companies in such great condition. As soon as I planted them they started growing, and are still growing now into winter, even after snow and frost.

Jackie

This was part of the "Waves of Purple Bearded Iris Collection." They arrived as expected and in great condition. I am very much looking forward to seeing them grow and bloom next spring. I also had an issue with my order, but Holland and Bulbs exceeded my expectations with their custom service and commitment to their customers.
