The world's most popular ornamental grass, Calamagrostis acutiflora 'Karl Foerster' (Feather Reed Grass) has a strong upright habit and blooms with showy flowers that ripen to tawny seed heads that decorate the plant through the fall and winter months.
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).
2001 Perennial Plant of the Year 48-60" tall x 24" wide (division propagated). Rather drought tolerant (but not quite xeric) and tolerating a wide range of garden soils. Feather Reed Grass has a wonderful upright growth habit, making it very useful to place behind perennials with a spreading or rounded shape. The feathery plumes emerge in early summer and ripen to handsome wheat-colored seed heads by fall. Cut back to 3” late spring. Scratch out old, dead canes from the center of the clump. Combine with Artemisia 'Powis Castle' or Russian Sage. Plant in groups of three or five for best effect.
Flat of 9 plants will cover 18 square feet when planted together
