Drumstick allium plants reach heights of 24 to 36 inches (61 to 91.5 cm), making them hard to miss. Bright beds, borders, wildflower gardens, and rock gardens are all enhanced by the beauty of the showy drumstick allium flowers. You may even grow them in a mixed planting with tulips, daffodils, and other spring bloomers. Drumstick allium bulbs can also be planted in containers. Drumstick allium blooms are perfect for cut flower arrangements due to their robust, long stems.
Plant drumstick allium bulbs in sandy, well-drained soil that has been improved with compost or other organic matter in the spring or the fall. Plants that grow drumstick allium need direct sunlight. Avoid planting bulbs in wet, poorly drained areas since they will likely decay. Plant the bulbs 2 to 4 inches deep (5 to 10 cm.). Place bulbs 4 to 6 inches (10 to 15 cm) apart.
How deep should drumstick allium bulbs be planted?
The summertime drumstick allium produces egg-shaped flowers that emerge green, bloom and turn pink, and then turn clover red-purple. These plants look good in a bed or border, especially when they peep up through other flowers, like roses, to conceal their bland foliage. They offer value to the garden with their vertical presence and striking bloom shape, and they freely naturalize.
Characteristics to Note
Midsummer sees the lovely purple-red drumsticks bloom, and as the summer goes on, they start to fade.
Plant in healthy, well-drained soil in direct sunlight in the fall, 2 to 4 inches deep.
Propagation
When ready or in the spring, plant seeds in containers in a cold frame. Some Allium plants need two years to sprout. Cut off offsets in the fall.
Problems
Damp circumstances cause bulbs to decay. There may be white rot, mildew, rust, smut, and different fungal leaf marks. Thrips and onion flies are other potential causes.
ALLIUM PLANTING GUIDE
The allium family includes the chives in your herb garden, which are little, fluffy purple balls that bees and butterflies adore. Alliums used as ornaments, however, are anything but tiny. Big drama is what these enormous globes on tall stems are all about in your landscape. Alliums are a great choice if you are growing bulbs with kids since they enjoy the fact that when these blooms bloom, they frequently tower over them.
Garden & Container Planting
Alliums require a cold spell to establish their roots and get ready for spring, just like other flower bulbs do. So it’s time to start planting as soon as the first chill of fall appears in the air.
Although flower bulbs are hardy and simple to grow, they detest getting their feet wet since they can quickly decay if left to “bathe” in water. Therefore, avoid at all costs moist soil. this refers to locations where puddles are still visible 5–6 hours after a downpour. You can also improve possibly wet soil by incorporating organic material like peat, bark, or manure. The same motto applies when planting bulbs in containers: drainage, drainage, and more drainage. Purchase a container that has at least a few drainage holes at the bottom.
Because alliums require a lot of light to flourish, locations with less than full sun are not suitable.
Alliums must be buried deeply enough so that changes in the temperature above ground—either too warm or too cold—won’t influence them. Because containers can’t protect bulbs as well as mother earth can, it may be preferable to let your containers spend the winter indoors in a cool, dark, well-ventilated area where the temperature won’t rise above 60 degrees Fahrenheit, such as an unheated basement or garage, if you live in one of the hardiness zones 3 to 7.
The bulb is placed at the bottom of the hole with its sharp end facing up, and a hole three times as deep as the bulb’s height is dug to determine the optimal depth. When competing for nutrients with other bulbs, alliums perform worse, therefore it’s best to space them 6 to 8 inches apart.
After planting, it’s crucial to give the bulbs plenty of water to help them settle and develop roots rapidly, but after that, you won’t need to water them again. All that’s left to do is wait patiently for spring to come and surprise you with the fruits of your labor and for winter to work its magic underground.
Alliums don’t typically need watering during the flowering season, but you can water them if there hasn’t been any rain for three to five days.
Don’t trim the foliage of alliums right away after they have stopped flowering; through photosynthesis, the leaves will produce the nutrition the bulb needs for its subsequent growing season. The leaves will naturally turn yellow and die back after a few weeks, at which point you can remove it. The bulb will now enter dormancy and won’t require watering again until the following spring.
How to plant alliums in your garden:
- Wait till the soil is 60°F or colder before planting. This will happen around September or October in the North and October or November in the South.
- Choose a location in your garden that has soil that drains properly and receives full sun.
- The allium bulbs should be planted with their pointed ends facing up, 4 to 8 inches deep, and 6 to 8 inches apart.
- once, and then wait until spring.
- Don’t remove the leaf from alliums after they bloom. Remove it once it has entirely withered and become yellow.
How to plant alliums in containers:
- Wait until the soil temperature is at least 60 degrees Fahrenheit and the weather is chilly. This will happen around September or October in the North and October or November in the South.
- Choose a location in your garden that receives direct sun.
- Find a container with good drainage, fill it with loose soil, and make sure that water won’t collect and pool at the bottom.
- The allium bulbs should be buried in the ground with their pointed ends facing up, 4 to 8 inches deep, and 6 to 8 inches apart. You can try putting the bulbs closer together since containers frequently have a small amount of room, but make sure they never touch.
- If you reside in hardiness zones 3–7, you can water well once and wait until spring, or you can bring the containers inside and let them spend the winter in a cool place like an unheated garage or basement.
Special effects
You can choose the extremely regulated technique if you prefer order and cleanliness or if you want to maximize the wow-factor alliums can provide to your garden or container. Grow your alliums in straight rows with roughly 10 bulbs spaced closely apart (you might want to add some fertilizer to the soil to make sure they still get all the nutrients they need). Growing a row of 10 taller alliums, like Purple Sensation, behind a row of 10 slightly shorter ones, like Azureum, can produce an even more dramatic effect.
Spreads drumstick allium?
Benefits: Unlike most other alliums, this late-blooming ornamental onion features spherical, purple flowers that bloom in early to midsummer. The long-lasting flowers are wonderful for bouquets and the garden. Drumstick alliums may withstand deer damage. Pollinators are drawn to the blossoms.
Early to midsummer sees the appearance of 1-inch-long, oval-shaped purple flowers on stiff, slender stems that are 18 to 36 inches tall. These allium blossoms start out green before changing to pink and finally purple as they open and develop. suitable flowers for dry or fresh bouquets.
Foliage: In the spring, a clump of grassy, gray-green leaves up to 14 inches long can be seen.
Drumstick alliums are ideally cultivated in drifts or clumps of 12 or more for aesthetic purposes. In order for the purple flowers of the bulbs to emerge among the other plants, the bulbs can also be dispersed among perennials. Grow in bright or partial sunlight. Better is a full sun. Alliums favor fertile, well-drained soil. Drumstick alliums grow from bulbs that were sown in the fall. Bulbs should be buried 3 to 5 inches deep. By seed, these bulbs easily naturalize (spread). Drumstick allium should be deadheaded before setting seed if you don’t want it to spread. Allow the foliage to naturally die back. 48th USDA Zone.

Does drumstick allium grow year round?
The autumn season is a great opportunity to consider your garden again. I frequently find myself analyzing and planning new plant combinations, regions that want editing, or a spot that requires a punch. Fortunately, the fall is a season where a little preparation and forethought will pay off in the spring and summer following.
The Drumstick Allium is a plant that I have grown to adore over the past few years. A dramatic addition to a perennial border, cutting garden, or spring bulb planter is this bulbous perennial. The main growing requirements for this plant are the same as for the giant, globe-like alliums you may already have in your garden: full to part sun and a well-drained soil. But this stunning perennial varies from its much larger cousin in that it is smaller, more slender, and goes well with a variety of other perennials.
An egg-sized burgundy bloom, perched atop a stick-straight, slender 2-3′ stock, adorns the drumstick allium. Mid-May sees the unassuming bud appear, followed by a deep green flower that, over the course of a week, turns into a rosy-burgundy flower that the honeybees enjoy. In the Midwest, the teardrop-shaped bloom lasts throughout June and July.
In order to give the landscape an additional level of color and texture, I match this ornamental onion (or leek, depending on who you ask) with perennials that it can tower over. The blue-purple bloom of perennials like “Havana Blue” geranium and “Walker’s Low” catmint is enhanced by the allium’s rosy-burgundy color. Additionally, I’ve discovered that it contrasts beautifully with the vibrant chartreuse of newly blooming Amsoina hubirchtii. Due of the allium’s magnificent grandeur, it is best planted with a taller perennial or hedge in the backdrop to assist accentuate its beauty. On that topic, for the most striking effect, I would also advise planting in a mass or a grouping of 10 to 15.
With a diameter of around a quarter, this bulb is extremely easy to plant. I just create a 1″ x 1″ hole that is 3 to 4 deep, add 10 of the bulbs, cover it, and repeat. It couldn’t be much simpler. From the end of September to the week before Thanksgiving, I usually plant my bulbs. This bulb is ideal if, like me, you have deer lurking around every corner because the smell of onion and garlic scares them away.
This bulb, which is about the size of a quarter, is easy to plant. See Planting and Storing Bulbs for more information on how to plant bulbs.
The tall, straight stems of the drumstick allium make it the ideal cut flower, whether used alone or in a bouquet with garden roses or dahlias.
Allium sphaerocephalon is relatively affordable in contrast to other bulbs, so I really plant them by the thousands. For a garden that needs a splash of color and texture next spring and for years to come, I cannot suggest it enough.
An eye-catching addition to a perennial border, cutting garden, or spring bulb planter is a drumstick allium. Many florists, including Mary Ernst McColgan of Rose Bredl Flowers in Columbus, Ohio, love this allium as well.

Spread alliums?
Spread alliums? Yes, the plant’s bulbs and seeds will grow and spread without much help from you. Typically, they will disperse at their own rate and stay put until they are moved or split.
What depth should allium plants be buried?
Consider your garden space when choose which alliums to cultivate. Will you be bulk-planting in pots or growing in drifts through the border? as a component of a structured planting plan for prairies? Additionally, it’s crucial to consider the color of your alliums. Although most allium blossoms are purple, some are also blue, white, yellow, and pink in color. Also take into account the size of your allium—both the size of the flowers and the plant’s overall height. Allium flowers can range in size from a few centimeters to over 20 cm (8 in) in diameter, and their eights can also differ greatly.
Planting large, tall alliums singly or in drifts works nicely for varieties like “Purple Rain” and “Globemaster.” Allium christophii and other shorter variants grow well in containers. In prairie planting designs, drumstick alliums like Allium sphaerocephalon look fantastic.
Where to plant alliums
Alliums thrive in a sunny location with excellent soil drainage. They don’t care what kind of soil it is. Plant higher-growing cultivars in the back of a border and lower-growing varieties up front. Although alliums do well in containers, their strappy foliage can become ugly after flowering.
The leaves of alliums develop before the flowers do. As a result, they are frequently better suited to the center of a border where the faded foliage would be hidden and the flowers will put on a display. Plant alliums among attractive grasses and perennials to hide the fading foliage.
Grow alliums in broad drifts through the border or let them naturally grow in your lawn for a striking show.
How to plant alliums
Plant allium bulbs in the fall, at least four times their size deep (at least 15cm deep). It is preferable to plant them deeply rather than superficially.
There is no need to water them in if the soil is damp. Poor soils should be fertilized with a balanced fertilizer in the spring as growth begins to show.
