Collection: Allium Bulbs

The best online selection of colorful allium bulbs

Allium is a genus of flowering plants that consists of hundreds of species! Garlic, onions, scallions, shallots, and leeks are all card-carrying members of the massive allium family. But did you know that alliums can also be extraordinary flowers? It's true! Many alliums produce flowers that typically have six petal-like tepals. The curious flowers appear on a tall, sturdy stalk in a globe-like cluster. Depending on the species, the anthers and pollen color will vary. Heights will also vary between varieties, ranging anywhere form five inches to as towering as four feet! To see some of the variations, check out our Giant Spider Alliums, Small Blue Caeruleum, Tall Schubertii, and our Drumstick Allium bulbs, just to name a few of our more than 20 allium varieties.

Allium bulbs are easy to plant

While it's plain to see the aesthetic appeal of flowering alliums, the ease of planting should not be overlooked. Alliums are traditionally planted in the fall for late spring and early summer blooms. If possible, select a site in your yard that will receive full sun. Like most bulbs, alliums thrive in sun. However, they can be successfully grown in partial shade as well. Your soil should have proper drainage. In most cases, you will want to fertilize your allium planting site with bulb food to help ensure that the bulbs are properly established. Dig a hole that is about twice as deep as the height of the bulb. Each hole should be around six to eight inches apart. Be sure to plant allium bulbs pointy end up! After you have planted your bulbs, be sure to water them sufficiently. You can also successfully plant alliums indoors. Providing your alliums have proper drainage and sunlight, they will cheerfully reappear year after year. Not only that, but their slim, vertical shape takes up very little ground space, leaving you room to keep them company with accent plants such as geraniums, hostas, irises, or peonies.

Allium bulbs make wonderful floral arrangements

Allium flowers symbolize unity, prosperity, patience, and good fortune. All wonderful things to represent in your yard or in a statement-making cut flower arrangement or bouquet! Whether, fresh or dried, alliums make spectacular, bold statements in floral arrangements, so be sure to cut some for inside.
