The smooth stems, sometimes tinged with reddish or purple hues, support dark green, oval-to-lanceolate leaves with serrated edges. These leaves can grow up to seven inches long and add a lush backdrop to the star of the show: the flowers.<\/p>\n\n\n\n<p>Blooming from mid-summer to autumn, Helianthus decapetalus produces a profusion of cheerful, daisy-like flowers.
