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).

Details
48" tall x 24" wide (division propagated). This plant is the frosting on the cake for any garden, pleasing us by adding texture and color over the entire growing season. The stiff gray-blue leaves are very striking. They provide the foundation for the ornamental 4' tall flower spikes that shoot up and ripen to a soft brown by midsummer. Cut back in April to encourage vigorous new growth.

Flat of 9 plants will cover 18 square feet when planted together
