Rudbeckia fulgida Goldsturm, commonly known as Black-eyed Susan, stands out as a garden favourite. This cheerful perennial brightens landscapes with its golden-yellow blooms and easy-going nature. As a reliable choice for vibrant summer colour, it’s become a staple in modern gardens.
Appearance and Characteristics
Goldsturm forms neat clumps of dark green foliage, reaching 60-75cm (24-30 inches) tall and spreading 50cm (18-20 inches) wide. Its daisy-like flowers measure 10cm (4 inches) across, featuring bright yellow petals surrounding a prominent dark brown central cone. The flowers bloom profusely from mid-summer to autumn (August to October), providing a long season of interest. The ‘Goldsturm’ variety particularly impresses gardeners with its compact habit and abundant flowers.
Ideal Growing Conditions
This adaptable plant thrives in full sun but tolerates partial shade. It prefers moderately fertile, moist, well-drained soil but adapts to various soil types, including clay and sandy soils. Optimal growth occurs in locations with 6 hours or more of direct sunlight. Goldsturm performs best in temperatures between -22°C and 30°C (-11°F and 86°F).
Planting and Care Tips
Plant Goldsturm in spring or autumn, spacing plants 50cm (18 inches) apart. Water regularly, especially during dry periods, until established. Adding well-rotted compost or organic matter improves soil drainage and moisture retention. Deadhead spent flowers to encourage more blooms and prevent self-seeding. Although generally pest-resistant, aphids and leaf spot can sometimes occur. Most gardeners successfully treat these issues with insecticidal soap or by removing affected foliage.
Garden Uses
Goldsturm’s bright yellow blooms make a striking addition to borders, cottage gardens, prairie plantings, and container displays. They combine beautifully with other late-summer flowering perennials like Coneflower, Monarda, Yarrow, and ornamental grasses. These flowers prove invaluable in butterfly gardens, attracting various pollinators throughout their blooming season. They also make excellent cut flowers, lasting well in arrangements.
Maintenance and Winter Care
Goldsturm requires minimal maintenance throughout the growing season. Cut back stems to 8-10cm (3-4 inches) before winter or leave them standing to provide food for birds and trim in spring. Leaving the seed heads allows for natural reseeding, but deadheading helps control spread. Divide clumps every two to four years in spring or autumn to maintain vigour.
Benefits of Growing Rudbeckia Goldsturm
This versatile plant offers numerous advantages for gardeners. Its long blooming period extends from summer through autumn, providing consistent colour. The flowers attract beneficial insects, supporting garden biodiversity. Deer and rabbits typically avoid these plants, making them perfect for wildlife-prone areas. Once established, they show good drought tolerance, reducing watering needs. Their easy-care nature suits both novice and experienced gardeners.
Similar Varieties
While Goldsturm remains a top choice, several other Rudbeckia varieties offer similar qualities. ‘Anthony Brooks’ and ‘Goldschirm’ present almost identical traits. Rudbeckia fulgida var. deamii grows slightly taller with smaller, more numerous flowers. For container growing, the compact ‘Little Goldstar’ proves especially suitable.
Conclusion
Rudbeckia fulgida Goldsturm deserves its reputation as a garden star. Its vibrant colour, long blooming season, and low-maintenance nature make it a valuable addition to any garden. Whether creating a vibrant border, attracting pollinators, or seeking easy-care blooms, Goldsturm delivers outstanding results. Its adaptability and widespread availability ensure its continued popularity among gardeners of all experience levels.
