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 Guides

Planting And Growing Tips For Prairie Clover (Dalea) a genus of New World wildflowers that includes both woody and herbaceous species. These plants are legumes and fix nitrogen into the soil. Preferred growing conditions:

  • Plant in most any soil including clay with full sun conditions.
  • Mulching is not needed.
  • Water regularly the first growing season to establish the plants. Once established, infrequent, deep watering is fine.
  • Fertilizing is not needed, as they are legumes that fix nitrogen from the air and put it into the soil.
  • Special comments:

  • Allow the herbaceous types to re-seed. Seeds are also eaten by songbirds, so deadheading is not recommended.
