With its bright golden daisy blooms and dark central cones, Rudbeckia ‘Goldsturm’ lights up gardens in late summer. This popular coneflower provides a bold pop of color when many other perennials are fading. But just how tall does this stellar performer grow?
Rudbeckia ‘Goldsturm’ earns its stellar reputation with abundant long-lasting flowers and easy care. Before planting this eye-catching perennial it helps to understand its expected mature size.
A Compact, Clump-Forming Coneflower
While species like R. hirta can spread aggressively, ‘Goldsturm’ forms a tidy, upright clump This well-behaved cultivar was introduced in 1937 and won Perennial Plant of the Year in 1999.
‘Goldsturm’ emerges in spring as a mound of oblong, hairy green leaves. Flower stalks appear in early summer, elongating through midsummer. The clumps typically reach 2-3 feet tall and 1-2 feet wide when mature.
Achieving Maximum Bloom Height
Given proper growing conditions, ‘Goldsturm’ will achieve its full height potential to showcase plenty of golden daisy blooms. Here are some tips for success:
-
Site in full sun and well-drained soil. At least 6 hours of direct sun keeps growth upright.
-
Provide average moisture. Water during drought, but avoid soggy soil.
-
Stake tall stems if needed. Sturdy stakes prevent flopping in rich soil and shade.
-
Deadhead spent blooms to extend flowering into fall.
-
Divide congested clumps in early spring every 3-4 years. This encourages vigorous growth.
-
Apply a balanced fertilizer or compost in spring to fuel growth. Avoid high nitrogen.
Height Fluctuations and Variability
While typically topping out around 2-3 feet, the ultimate height of ‘Goldsturm’ depends on several factors:
-
Age of the plant. Young plants may not achieve maximum height until 3+ years old.
-
Growing conditions. Poor soil, drought, or too much shade can reduce height.
-
Bloom stage. Flowering stems elongate the overall height. Expect shorter foliage-only height early in the season.
-
Regional variability. Some strains finish slightly shorter or taller than the typical range.
-
Individual variability. Even in ideal conditions, mature heights vary across different plants.
Cutting Back for Shorter Height
For a more compact ‘Goldsturm’, try cutting it back by half in early summer. This pruning reduces the mature height to 1-1.5 feet. Time it just after the initial spring flush of growth when foliage reaches 6-12 inches tall.
Deadheading spent blooms and trimming off leggy stems later in the season can also maintain a tidy size. Just be sure to stop pruning by early September so plants can prepare for winter.
Enjoying Well-Behaved Vertical Accent
With its upright growth habit, bright flowers, and dark centers, ‘Goldsturm’ coneflower provides great vertical contrast in beds and borders. Tucking shorter plants in front shows off its mature size.
By selecting a Rudbeckia ‘Goldsturm’ of ideal age and providing good growing conditions, you can fully enjoy all the height and floriferousness this stellar perennial has to offer!
