Using Allium Flower Bulbs in Garden Design

Allium flower bulbs are very versatile, and a great addition to flower bulb gardens and mixed perennial beds. You can perk up borders with a mixed selection of allium bulbs or keep it simple with varietal groupings. Because they bloom after many spring-blooming flower bulbs, like daffodils, alliums draw the eye away from the fading bulb foliage. Alliums are also excellent at attracting pollinators to the garden.

Allium Bulbs: Getting the Most out of Your Purchase

Alliums, like many other spring-blooming flower bulbs, are easy to grow and require very little maintenance. By following a few simple steps, you'll have eye-catching flowers in late spring or early summer.

When to Plant Allium Bulbs

Plant alliums in the fall, at the same time you plant other spring-blooming flower bulbs, like tulips, daffodils and hyacinths.

Where to Plant Allium Bulbs

Allium flower bulbs should be planted in rich, well-drained soil. If the soil doesn't drain well, the bulbs could rot. Allium bulbs also need full sun, or 6-8 hours of direct sunlight daily. Most allium bulbs are hardy in zones 4-9.

How to Plant Allium Bulbs

The general rule of thumb for planting flower bulbs applies to allium bulbs. Plant the bulbs two to three times deep as the bulb is tall. Smaller varieties of allium should be planted 4 inches deep while the larger varieties should be planted 7-8 inches deep.

How to Grow Allium Flowers

Alliums are members of the onion family, so their fragrance may be rather pungent. Deer tend to avoid them. Alliums also work well as cut flowers.
