Think of the romantic notion: “He loves me, he loves me not,” as a yellow petal is pulled off a daisy-like flower. The broad aster family includes various genera, including groundsels and lessingia. Groundsels (Senecio genus) have large flowers and phyllaries in one row that distinguish them from goldenrod. Sierra butterweed, also a type of Senecio, plays a major role of the meadow wildflower display in Tuolumne Meadows. Sierra lessingia (Lessingia genus), colored purple rather than yellow, grows abundantly along roadsides and on dry, open flats and talus slopes in Yosemite Valley—where it was first discovered.
