'Goldsturm' black-eyed Susan is a cultivar and is one of the most popular perennials in cultivation. It won the Perennial Plant of the Year Award in 1999 and the Award of Garden Merit of the Royal Horticultural Society in 1993. This herbaceous perennial has a clumping habit with erect stems that reach a height of 18 to 24 inches. The plant has bold, dark green foliage, and the flower has rich yellow petal rays with a dark brown center disk. It is a nonstop show of flowers from mid-summer until the first frosts of fall. This cultivar is a member of the Asteraceae or daisy family. 'Goldsturm' was first introduced in 1937. The name, 'Goldsturm,' is German and means "storm of gold" or "golden storm." 'Goldsturm' black-eye Susan performs best in full sun and moist, well-drained soils in hardiness zones 3-9. It is tolerant of partial shade and, once established, it will become more drought-tolerant. To prevent foliar disease, good air circulation is needed, particularly in humid climates. Deadheading spent blooms will promote reblooming throughout the season. Remove the dead foliage in the fall. The plant will spread via its rhizomes, and it may also be propagated by division. 'Goldsturm' is easy to grow and requires very little maintenance. The cultivar is more compact than other species and has large flowers measuring up to 4 inches in diameter. Butterflies and bees are attracted to its blooms. Consider this cultivar as a mass planting in a border, cottage garden, meadow, or naturalized area. This reblooming and long-lasting flower will add bold color to any late summer and fall garden.
