Goldquelle Coneflower (Rudbeckia laciniata 'Goldquelle') is an old-fashioned, tall but compact perennial, also known as Gold Drops. With its double blossoms, late bloom time and attractive divided leaves it deserves more attention. Some people confuse this with the older variety "Golden Glow', which is taller, more invasive, floppier, and more attractive to aphids. The flower heads of this double-flowered perennial are packed with lemon-yellow petals and grow on stems 3 ft. high.Goldquelle Coneflower Rudbeckia laciniata
