Buying allium bulbs?
Do you want to buy allium bulbs for your garden? You have come to the right place. The allium, also known as the ornamental onion, is a real eye-catcher with its purple spheres on tall stems.
We grow and select our allium bulbs with care, right here in the heart of the "Bollenstreek" (Dutch bulb region). This way, you can be sure that you are getting top-quality, fresh bulbs directly from the grower.
Why buy alliums for your garden?
The allium is perhaps the easiest way to give your garden a playful and modern character. The large, spherical flowers float like purple balls above your border and bloom in May and June. Exactly in the period between the spring-flowering and summer-flowering plants! This keeps your garden beautifully colorful throughout the spring.
But there are more benefits! Bees and butterflies love ornamental onions, so by adding allium bulbs to your border, you are immediately helping the insects in your garden. Moreover, the allium is hardy. Once planted, it comes back year after year. Highly recommended, if you ask us!
Which popular allium varieties are there?
Alliums come in various shapes and sizes. But that is precisely the advantage of this eye-catcher, as you can combine them endlessly. These are the most popular ones at the moment:
- Allium Giganteum: The name says it all: the Allium Giganteum is the giant among ornamental onions. With flower stems up to one and a half meters tall and large purple flower heads, this is the variety for those who want to make an impression at the back of the border.
- Allium Purple Sensation: The Purple Sensation is a true classic: deep purple flowers on sturdy stems of about 80 centimeters. This variety also naturalizes easily, meaning you get more enjoyment from it every year.
- Allium Sphaerocephalon: The Allium Sphaerocephalon is also known as "drumstick allium" because of its smaller, egg-shaped flowers that color from green to wine red. Perfect among ornamental grasses and perennials for a natural effect.
When should you plant allium bulbs?
Plant allium bulbs in the autumn, from September through November. The bulb needs the winter cold to sprout well in the spring. Plant the bulbs in a sunny spot in well-drained soil, about three times as deep as the bulb is tall. For most varieties, this means a depth of about 10 to 15 centimeters, with the point facing up. Are you planting multiple bulbs? Then keep about 20 to 30 centimeters of distance between them.
In our blog 'when to plant allium?' you can read step by step how to do it, including the tips that we use ourselves at the nursery.
When does the allium bloom?
The allium blooms in May and June, exactly in the period between the spring bulbs and the summer bloomers. When exactly the ornamental onion opens depends on the variety. Early varieties like the Purple Sensation already turn purple at the beginning of May, while the drumstick alliums only reach their peak at the end of June. If you combine different varieties, you can enjoy those characteristic purple spheres for weeks on end!
Brenda's tip: Has your allium finished flowering? Don't cut it away immediately. The seed head that remains is perhaps just as beautiful as the flower itself. It will stand gracefully in your border all summer long.
Which flowers do you combine alliums with?
Ornamental alliums look their best among other plants and flowers. There is a practical reason for this, as the allium's foliage dies back early in the season. Therefore, plant them among perennials like Geraniums or Salvias, as they hide the dying leaves while the purple spheres continue to float above them.
Also beautiful: alliums among ornamental grasses for a more natural look. And do you like romance? Peonies bloom in exactly the same period, so together they provide the highlight of your border as early as the end of May.
