USDA Plant Hardiness Zones

To help gardeners understand which plants will grow well for them, the entire USA has been segmented into ‘Plant Hardiness Zones’. Knowing your zone number is helpful when shopping for plants because:

  • Cold-area gardeners can avoid buying plants that simply won’t survive their lowest winter temperatures.
  • Warm-area gardeners can steer clear of plants that need a period of cold weather in order to bloom again.

Plant Information

More compact than most amsonias, Blue Ice also boasts larger flowers in a deeper color than other varieties. The star-shaped, dark lavender-blue flowers are about 3/4" across and appear in late spring or early summer. The leaves are relatively broad, resembling willow leaves. At just 12 to 16" high, Blue Ice combines well with other perennials without overwhelming them, and the shorter stems are less prone to flopping than taller varieties.

Amsonias form upright mounds of feathery foliage, topped in spring by delicate blue blossoms. They're easy to grow, preferring full sun to part shade and moist, rich soil. The feathery foliage of taller varieties make a pretty backdrop for other perennials, and the leaves turns a brilliant yellow in fall.

    Comments about American Meadows Blue Star Flower Blue Ice:

    Bought this 2 years ago, has yet to bloom. Seems to take my dog's occasional abuse (dog loves to trample the patio plants from time to time!). I still have hope - aside from a few early casualties, my other purchases from 2 years ago just bloomed this year. In the mean time, will reread tag instructions/care and enjoy the bloomers!

    Q & A

    Plant With These:

    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).
