When do I plant Allium bulbs?

Plant Allium bulbs in the fall season. Plant as deep into the ground as three times the width of the bulb. Do not plant in frozen ground, as the bulbs will not have time to root.

Alliums will grow in USDA hardiness zones 3 through 9. They are low maintenance, easy to grow perennials that come in a wide variety of colors. Alliums are also known as ornamental onions. They'll bloom spring to fall, depending on the plants selected for propagation. Deer especially do not like the taste of these, so there is little concern that they will be eaten.
