1.Rudbeckia Goldstrum — Overview
Rudbeckia fulgida 'Goldstrum', commonly known as Goldsturm Black-Eyed Susan, is a popular and robust perennial cultivar of Rudbeckia fulgida. This cultivar is celebrated for its prolific blooming and striking visual appeal, making it a staple in many perennial gardens. It typically grows to a height of 2-3 feet (60-90 cm) with a spread of 1-2 feet (30-60 cm), forming upright clumps of dark green, slightly rough-textured foliage. The leaves are ovate to lanceolate, with toothed margins, and are arranged alternately on the stems.
The most distinctive feature of 'Goldstrum' is its abundant, daisy-like flowers that appear from mid-summer through fall. Each flower boasts bright golden-yellow ray florets that surround a prominent, dark brown to black, cone-shaped center (disk florets). This contrast between the vibrant petals and the dark cone is highly attractive to pollinators. The flowers are typically 3-4 inches (7.5-10 cm) in diameter.
'Goldstrum' is known for its exceptional vigor, long blooming period, and good disease resistance, particularly to powdery mildew, which can affect other Rudbeckia species. It is a hardy plant, suitable for USDA hardiness zones 3-9, and thrives in full sun to partial shade. Its upright habit and long-lasting blooms make it an excellent choice for borders, mass plantings, cut flower gardens, and naturalistic landscapes. The seed heads provide winter interest and a food source for birds.

- Amend heavy clay soils with compost to improve drainage.
- Space plants 1-2 feet apart to allow for mature growth.
- Water regularly, especially during dry periods, but avoid overwatering.
- Deadheading spent flowers can encourage reblooming and prolong the flowering season.
- In late fall or early spring, cut back the dead foliage to the ground to promote new growth.
- Division is typically not necessary for several years, but can be done in early spring if the clumps become overcrowded or lose vigor.
- This plant is relatively low-maintenance once established and is drought-tolerant.
