The alliums are a large genus and probably best known for the edible members of its family. Some of which include chives, onions, garlic, and the leeks. Trying to decide which variety to plant can be a daunting task, due to the fact that there are so many different choices.
When planted in groups they provide drama to your late spring or early summer garden. They make excellent additions to your beds and or mixed borders of iris, peonies, bleeding hearts, daylilies and hostas by giving some height and airy lightness to the mix. The smaller species are well suited for use in your rock garden.
Bulbs should be planted in the fall, the same time you are planting the rest of your spring blooming bulbs.
Most of the alliums have either grass-like or cylindrcial and hollow leaves. When bruised, bulbs give off an onion-scent much like that of its related cousins, the onions.
Alliums usually bloom in the spring and summer, depending on the variety. The small flowers are borne in either a few to many-flowered umbels. Colors can be white, yellow, pink, red, violet, or blue. Flowers can last for weeks.
The range of flowers is extensive, from the dwarfs to the giganteum, which produce a 4-6 inch round umbel of flowers on 4 foot stems. They all make excellent cut flowers, and are a great addition when used in your dried arrangements.
