USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).

Planting and Growing Allium (Ornamental Onion) Plants

Allium (Ornamental Onion) is a large genus of culinary and ornamental plants with deep green folliage and excellent deer and rabbit resistance.

  • Bulb types are late spring/early summer bloomers that go summer dormant.
  • Late summer/early fall bloomers (like 'Millennium') are not bulbous and grow actively over the spring and summer months.
  • Plant in most any type of soil including clay, with full to part sun. Mulch with common mulch materials, such as bark, pine needles or gravel.
  • Allium prefers dry to moderate soil moisture once established.
  • Cut bulb-types to ground level when foliage begins to turn yellow in summer. Cut non-bulb types to the ground in fall.
  • Fertilize lightly in fall with Yum Yum Mix/compost blend.
