The photo above shows alpine meadow groundsel as seen at Swampy Meadows at the southwest corner of Mt. Adams........August 8, 2004. Note the single flower atop the stem. This version of Packera streptanthifolia is typically found in moist, subalpine to alpine meadows. The other version is typically a plant of rocky to gravelly slopes, especially those that are near and above timberline on Mt. Adams.
