Organic allium flowerbulbs

The allium flowerbulbs that Bloemoloog offers are also known as ornamental onions. They are related to garlic and onion and belong to the Alliaceae family. With more than 1000 different varieties, of which approximately 100 are ornamental onions, allium offers a beautiful variety. These bulbous or half-round flowers often have star- or pearl-shaped flowers that grow on high and stable stems. In addition, there are also many low species that adorn the borders annually. In our range the height varies from 30 centimeters to one meter.

Plant them in groups, combined with the white 'Mount Everest' or the late-flowering 'Sphaerocephalon'. After flowering you can choose to leave the flowerbulbs in the ground, but you can also remove them from the ground for propagation during the summer months to separate the small bulbs and plant them separately in other places in the garden. As soon as October comes, you can put them back in the ground.

Allium's are beautiful additions to gardens and landscapes, and they provide a distinctive and architectural look. With their various flower shapes, colors and heights, ornamental onions can add a unique visual element to your outdoor space.

Flowerbulbs for bees

Allium's are loved by pollinating insects, such as bees and butterflies. Their flowers contain plenty of nectar and pollen, making them a valuable food source for these important pollinators. Adding ornamental onions to your garden can help create a thriving and vibrant environment and contribute to biodiversity.

Sustainable flowerbulbs

A special feature of ornamental onions is their long lifespan and durability. Most ornamental onions are perennials, meaning they return and bloom again year after year. They generally form sturdy bulbs underground, which store the energy and nutrients needed to survive the next growing season and produce flowers.

The durability of ornamental onions not only makes them cost-effective, but also an investment in the future of your garden. As the bulbs reproduce, they can spread and slowly form a larger clump, making your garden more and more impressive with age.

Care of the allium

Ornamental onions prefer well-drained soil and a sunny to semi-shaded position. Ornamental onions are generally hardy and require little water once established. After flowering, the spent flower stems can be removed, but it is advisable to leave the leaves so that the bulb can store energy for the next flowering cycle.

  • There is a wide range of flower bulbs that bloom in spring and mark the beginning of spring! In early spring you can enjoy beautiful flowers such as winter aconites, crocuses, daffodils, muscaris, star of Bethlehem and wood hyacinths. As spring progresses, the tulips and ornamental onions will take over the show and fill your garden with their display of colour.

    Benefits of organic flowerbulbs

    When you choose organic flowerbulbs you can be sure that no chemicals and pesticides end up in the garden. These pesticides are harmful to bees and ensure that bees can no longer find their way to a nesting site. As a result, more and more bee species have been added to the red list in recent years. Together we can do something about this!

    Important for wild bees

    Did you know that there are wild bees that lay eggs in their nests that hatch in early spring? These newborn insect helpers immediately start looking for food in the environment. There are also insects that have hibernated and are in dire need of a hearty breakfast; the blooming flowers where nectar and pollen can be found! Just after winter there is little green and edible food available for these insects and planting early flowering flower bulbs ensures that there is food and the insects can gain strength for the summer to come.

    Tips for a flowery garden

    Plant different types of flowers, each with its own flowering time so that flowers bloom throughout the spring and there is food for bees and other insects in the garden. Do you also want to arrange your garden/box in such a way that you can enjoy flowers and the bees throughout the spring? Feel free to send us a message or ask us at the market stall, we are happy to help you! Also aim for more biodiversity in the garden and enjoy the first flowers and colors in the garden after the cold and dark winter!

  • Spring bloomers are flowers that bloom in the spring, between January and May. There are many different types of spring flowering bulbs that are suitable for different types of gardens and soil types.

    Spring bloomers in the sun

    Many spring bloomers need a lot of sun to bloom and grow well for the following year. These flowers can be planted in full sun:

    • Crocus
    • Daffodils
    • Tulips

    Spring bloomers in the shade

    Some spring bloomers also grow and bloom well in the shade, such as:

    • Bluebells
    • Scillas
    • Winter aconite

    Spring bloomers in moist soil types:

    • Fritillaria (Meleagris)
    • Leucojum
    • Narcissus 'Poeticus'


    There are many different types of spring flowering bulbs that are suitable for different types of gardens and soil types. Whether a spring flowering plant can grow in the sun or shade depends on the specific species. Some people like to stand in dry soil and others prefer wet feet. So there is a suitable spring bloomer for every garden.

    Harvest time

    The flower bulbs are removed from the ground by the grower around July, after flowering. Products are first dried so that they can be stored properly until they can be planted in the fall and the bulbs can retain their quality. The flower bulbs are available from August to December at the Bloemologist.
