(formerly Haplopappus carthamoides)
The photo above shows a close-up view of the flower head of large-flowered goldenweed as seen from the Columbia Hills...............July 7, 2006.
Large-flowered goldenweed is a prostrate, perennial wildflower with one to several stems, large oblanceolate leaves, and wide flower heads surrounded by widely triangular bracts. The stems range from 5-60 cm in length. The basal leaves are tufted, spiny-toothed to entire, and generally 5-40 cm long and 5-40 mm wide. The stems may sometimes be very leafy, or instead, may show a reduction of leaf size and number up the stem.
The flower heads are solitary, yellow, and have both disk and ray flowers. The 0-30 ray flowers may not be readily noticeable, and may measure up to 7 mm long. The very numerous disk flowers range from 10-14 mm long. Blooms from late June into early August.
Large-flowered goldenweed is found on rocky flats and open, rocky or graveled slopes, often with sagebrush or in forest openings.
Large-flowered goldenweed is found mostly east of the Cascade summits of Washington and Oregon, to northwest Montana, central and southwest Idaho, and northeast Nevada.
In the Columbia River Gorge, it is found between the elevations of 400'-3000' near Hood River, OR and hence east.
