Allium General Information

Late blooming ornamental plants that work great with early flowering perennials. Do not plant too closely together since they multiply rapidly. Plant Alliums in full sun in early fall. Water well throughout the growing season. Please note: We are not permitted to ship Alliums to Idaho or the Washington counties of Adams, Benton, Franklin, Grant or Klickitat.

Allium Plant Care

The smaller varieties of Allium should be planted 4" deep and the larger varieties 7-8" deep. Spacing 6-8". Clumps may be lifted and divided in either spring or fall. Allium will tolerate most soils, but performs best in sandy soils. Add organic matter like compost to clay soils if needed to improve drainage and lighten the soil.
