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
15" tall (in flower) x 12" wide (division propagated). The intense blue coloration of 'Boulder Blue' foliage is a delight. Although not a well-known variety, this selection, made by Ted Kuettel of Golden, CO over 30 years ago, has proven itself in the harsh and erratic climate of Colorado's front range. A larger grower than 'Sea Urchin', 'Boulder Blue' is a showy, heavy bloomer with a nice upright habit. Grows easily in any moderately fertile garden soil.
