Solidago rugosa 'Fireworks'
A clump-forming cultivar of rough goldenrod selected for its fine, arching sprays that resemble fireworks. It performs best in full sun and average to moist soils and tolerates clay. Plants reach mid-border height and flower reliably in early fall in much of North America. Stems are sturdy for the height and the habit stays relatively compact compared to tall roadside goldenrods. Flowers support bees and butterflies. In trials it ranked among the strongest garden performers and resists common problems under typical conditions.
