Low pussy-toes observed near the Klickitat Breaks, Soda Springs Unit of the Klickitat Wildlife Area.........May 31, 2021.
Characteristics:
Low pussytoes are perennial wildflowers with floral scapes arising up to 3
cm high from a branching, woody base. This species is not stoloniferous. The
numerous basal and stem leaves are oblanceolate to linear-spatulate in shape,
measuring 8-30 mm long and up to 5 mm wide. The leaves and stems are fairly
densely covered with white woolly hairs.
The flower heads are solitary and fairly broad. The flowers
are imperfect, with the staminate and pistillate flowers found on separate plants.
The involucres of the staminate haeads are 5-7 mm high with ovate, obtuse bracts
that are brownish. The pistillate involucres are 12-15 mm high with lanceolate
to linear bracts that are brownish or reddish-brown tinged. The plants typically
bloom in the Columbia River Gorge from April into May.
Habitat:
Low pussytoes are plants of dry open places in the foothills
and lowlands.
Range:
Low pussytoes may be found from southern British Columbia south
along the east side of the Cascades and Sierra Nevada to southern California,
east to Montana, Nebraska, and Colorado.
In the Columbia River Gorge, Antennaria dimorpha is found
between the elevations of 200'-3000' from east of Bingen, WA and on east.
