Chamisso sedge is natives to western North America and is found in many types of habitats. It can tolerate drier conditions than most of our native sedges. It grows in wet prairies but also on forest edges.
This tall (up to 5 feet in flower) perennial grass is native to many western states and does well in a variety of habitats. The flowers are in spikes with long awns and turn golden brown in our mid-summer prairies looking impressive as they wave in the breeze. This is not a dominant grass of our Willamette Valley prairies but an important component to add diversity to a site
Because this is the dominant native bunchgrass in the upland prairies west of the Cascades from southern British Columbia to central California it is an easy choice for mass plantings. With its fine thread-like leaves of steely blue-gray that form tussocks 10 in. height, it is very beautiful too, even planted individually in the landscape. No concern over ecological invasiveness. Drought and deer resistant.
Willow dock is native to many moist habitats throughout the west. Its habitat value in our native western Oregon prairies is not as a pollinator plant (it is wind-pollinated) but as a larval host-plant for butterflies such as the rare Great Copper. Restoration efforts are underway in the Willamette Valley to restore populations by providing both the nectar source, Grindelia integrifolia (gumweed), and the host-plant willow dock.
