Goldsturm, Cherry Brandy, or Fulgida? How to Choose the Right Rudbeckia Variety by Height, Colour, and Lifespan
Goldsturm comes back every year. Cherry Brandy does not. Find out which rudbeckia cultivar suits your garden by species, height, and colour.
Most rudbeckia articles hand you a list of cultivar names and move on. That list is useful — but it hides the one decision that controls everything else: whether your rudbeckia returns next summer or quietly disappears over winter.
The answer comes from species, not cultivar name. Goldsturm is a cultivar of Rudbeckia fulgida, a true rhizomatous perennial that builds a larger clump each year. Cherry Brandy is a cultivar of R. hirta, a short-lived plant best treated as an annual and refreshed from seed. Both have golden flowers and dark central cones. Neither label tells you which is which without knowing the species behind the name.
This guide sorts rudbeckia varieties by species first — R. fulgida, R. hirta, and R. laciniata — then places the major cultivars within the correct species context. Once you understand the species, choosing by height, colour, and longevity becomes straightforward. For full growing guidance on soil prep, planting distances, and watering, see our Rudbeckia Growing Guide.
The Species Behind the Cultivar Name
Three species dominate garden rudbeckias. Identifying the right one predicts lifespan, spread pattern, and maintenance demands better than any cultivar comparison.
R. fulgida (orange coneflower) is the reliable perennial. It spreads by short rhizomes, building a tighter, denser clump each year. In Zones 3–9 it returns without intervention, year after year. The foliage is relatively smooth compared to the other species [1].
R. hirta (black-eyed Susan) is the source of almost all colourful rudbeckia cultivars — the warm reds, mahogany-ringed petals, and bicolour gradients that R. fulgida cannot produce. The trade-off is longevity. R. hirta is technically a biennial or short-lived perennial, but most garden cultivars behave as annuals: they flower hard in their first or second season, then die out. The plant self-seeds freely, so a patch often reappears — but you are growing a new, genetically distinct plant each time [3].
R. laciniata (cutleaf coneflower) is the tallest species. In cultivation it typically reaches 4–7 feet; wild specimens can exceed 9 feet. It spreads aggressively by underground rhizomes and suits larger spaces where it can naturalise [4].
Leaf shape provides fast field identification. R. hirta’s leaves are rough and bristly — hirta means “hairy” in Latin. R. fulgida’s leaves are smoother and more rounded. R. laciniata’s are deeply lobed and palmate, resembling a divided shrub leaf more than a typical coneflower [1].
| Species | Typical height | USDA Zones | Lifespan | Spread mechanism |
|---|---|---|---|---|
| R. fulgida | 2–3 ft | 3–9 | Reliably perennial (3+ years) | Short rhizomes (slow) |
| R. hirta | 1–4 ft | 3–9 | Annual / biennial | Self-seeds only |
| R. laciniata | 4–7 ft (9 ft wild) | 3–9 | Reliably perennial | Rhizomes (aggressive) |
R. fulgida — The Perennial Clumper
If you want rudbeckia that gets better with age, R. fulgida is the answer. Its rhizome-based spread creates a steadily expanding clump rather than a scattered colony, making it manageable in formal borders and meadow plantings alike. Divide clumps every three to four years in spring to prevent the centre from becoming woody and to maintain strong flowering. Our Rudbeckia Care Guide covers division timing, soil prep, and post-transplant care in full.
Goldsturm (R. fulgida var. sullivantii ‘Goldsturm’)
One misconception worth clearing up: Goldsturm is not its own species. It is a cultivar of R. fulgida variety sullivantii, named for American botanist William Starling Sullivant, who collected the first herbarium specimen in 1840. The cultivar was introduced in 1937, and var. sullivantii is now rarely sold separately because Goldsturm’s popularity eclipses it entirely [5].
In the garden, Goldsturm grows 2–3 feet tall with flowers up to 4 inches across — deep golden-yellow rays surrounding a dark brownish-black central cone. It blooms from mid-August through October, handles drought once its root system establishes, and works in cottage gardens, prairie plantings, and pollinator beds. The Royal Horticultural Society awarded it an Award of Garden Merit in 1993 [6].
R. fulgida var. deamii
This is the practical alternative to Goldsturm for gardeners who want more coverage and better drought resilience. Var. deamii grows to around 30 inches with a more open, branching habit. Its flowers are smaller — about 2 inches across — but considerably more numerous, blanketing the plant in a dense cascade of gold from mid-August through October. The RHS recognises it with an Award of Garden Merit, and its open form looks naturally relaxed in informal plantings [12].
‘Little Goldstar’
At around 20 inches tall, this compact form of R. fulgida var. sullivantii is the choice for small gardens and containers. It produces the same deep-golden flowers as Goldsturm at roughly half the height, and NC State Extension notes resistance to southern blight — a fungal disease that can devastate rudbeckia colonies in warm, humid climates [2].
‘American Gold Rush’
Named 2023 Perennial Plant of the Year by the Perennial Plant Association and a 2020 All-America Selections winner, this recent introduction solves a specific problem: Septoria leaf spot. The fungal disease causes black spotting and early defoliation in wet summers, and most rudbeckia cultivars are susceptible. American Gold Rush was bred with narrow, hairy foliage specifically for resistance to this pathogen — field trials showed no signs of fungal damage even in persistently humid conditions. It grows 22–24 inches tall with a compact, upright habit and blooms July through September [8].
R. hirta — Big Colour, Short Life
R. hirta will not give you the same low-maintenance perennial patch as R. fulgida, but it delivers colours the perennial species cannot match. Warm reds, deep burgundy, mahogany-ringed petals, and bicolour gradients all originate here. Plan to replace these varieties annually, either by purchasing new transplants or allowing self-seeding to fill the patch.
The self-seeding habit means a patch can persist in the garden for years — but offspring are not identical to the parent, particularly with hybrid cultivars like Cherry Brandy or Denver Daisy. If you want consistent colour year after year, buy fresh plants or seed each season. For any problems that develop — black spotting, wilting, or heavy aphid pressure — consult our Rudbeckia Problems Guide, as R. hirta is more susceptible than the perennial species to Septoria leaf spot and aphid infestations.
Cherry Brandy
Confirmed by the Chicago Botanic Garden as a R. hirta selection, Cherry Brandy grows about 24 inches tall with 3–4 inch flowers in cherry-red to deep maroon petals, shading to burgundy at the base. It blooms from July through October [9]. The colour is completely outside the R. fulgida palette — if you want it, plan to purchase or grow it again next season. In mild zones (7–8) with good drainage it sometimes overwinters, but reliable perennial performance should not be assumed.
Indian Summer
The largest flowers in the R. hirta group, up to 9 inches across, on plants reaching 24–36 inches. Indian Summer produces semi-double golden-yellow blooms with dark chocolate centres. An All-America Selections winner in 1995 and named 2000 Fresh Cut Flower of the Year, it remains one of the best cut-flower options in this species.

The distinguishing feature here is the central cone: light green rather than dark brown, creating a noticeably lighter and more open aesthetic — almost luminous when mass-planted. Bred in Germany and a Fleuroselect award winner, Prairie Sun reaches about 3 feet with flowers up to 5 inches across. The green centre gradually turns brown as seeds develop, so the look shifts through the season. Prairie Sun also contributed half the genetics of Denver Daisy.
Denver Daisy
Bred by Benary Seeds as a cross between R. hirta and Prairie Sun, introduced in 2009 as a Colorado Plant Select introduction. At 18–24 inches, it is one of the most compact R. hirta options, with distinctive flowers: a rich mahogany-red rim between the outer golden-yellow petals and the dark chocolate central cone [10]. One practical note: its hardiness is narrower than the parent species. Most R. hirta varieties survive Zone 3; Denver Daisy is rated Zones 6–9. Northern gardeners should treat it strictly as an annual.
Cappuccino
A shorter, warm-toned option at 17–20 inches, with bronze petals graduating to yellow at the tips and a dark brown disc. Cappuccino holds both an RHS Award of Garden Merit and a Fleuroselect Gold Medal [11]. For gardeners who want colour warmth without the full height of Indian Summer or the mahogany intensity of Cherry Brandy, it is a well-decorated middle-ground choice.
R. laciniata — When You Need Height
R. laciniata is the rudbeckia you plant when you need vertical structure. Regularly reaching 4–7 feet in cultivation, it belongs at the back of a border where shorter plants can sit in front without being overshadowed. Penn State Extension highlights it as a large statement plant suited to naturalistic and native plantings, particularly in meadow or cottage-style designs [7].
Two features set it apart from the other species. First, the leaves: deeply lobed and palmate, they look more like a cut-leaved perennial than typical rudbeckia foliage — a useful identification clue when shopping at nurseries. Second, the central cone: rather than the standard dark brown disc, R. laciniata produces a green-yellow dome that matures to a pincushion shape. The flower’s yellow rays droop slightly compared to R. fulgida’s upright petals, giving each bloom a more relaxed appearance at a distance.
The main practical consideration is spread. R. laciniata spreads by underground rhizome more aggressively than R. fulgida. Missouri Botanical Garden explicitly flags it as spreading in a way that can overwhelm smaller spaces [4]. In formal borders, contain it with root barriers or plan for annual division. In a large meadow or naturalistic planting, that same vigour becomes an asset.
‘Herbstsonne’ (Autumn Sun)
The most widely available cultivar, ‘Herbstsonne’ typically reaches 4–7 feet with 3–4 inch flowers and distinctive green central cones. It blooms from mid-summer through September and holds an RHS Award of Garden Merit. In the US, it is reliably perennial in Zones 5–9. The green cone is most prominent early in the season; it softens as seeds set. At the back of a mixed border alongside tall grasses, it creates a prairie-style effect that no shorter rudbeckia can replicate.
‘Golden Glow’ (R. laciniata var. hortensia)
A double-flowered form dating to around 1897, Golden Glow produces fluffy pompon flowers packed with golden-yellow petals — completely unlike the single-flowered species. At 5–7 feet, it matches Herbstsonne for stature but creates an entirely different flower character. It occasionally escapes cultivation and has naturalised in parts of North America, which speaks to its vigour. If you want rudbeckia height combined with double flowers, this is the cultivar to choose. The double form lacks the central cone entirely, giving the flower a chrysanthemum-like appearance rather than classic black-eyed Susan.

Frequently Asked Questions
Is Goldsturm an annual or a perennial?
Goldsturm is a reliably perennial cultivar of Rudbeckia fulgida var. sullivantii. It returns each year in Zones 3–9 by spreading from short rhizomes, building a larger clump over time. Divide every three to four years to prevent the centre from becoming woody. This is distinct from R. hirta cultivars like Cherry Brandy, which are typically treated as annuals.
What is the difference between Rudbeckia fulgida and hirta?
R. fulgida is a true long-lived perennial that spreads by rhizome and returns reliably each year. R. hirta is a biennial or short-lived perennial that self-seeds but rarely persists as the same plant beyond one or two seasons. Leaf texture gives you a quick identification: R. hirta’s leaves are noticeably rough and hairy (hirta means “hairy”), while R. fulgida’s leaves are smoother and more rounded. For colour, R. fulgida produces only golden-yellow flowers, while R. hirta cultivars extend to red, mahogany, bronze, and orange.
Is Cherry Brandy a perennial?
Cherry Brandy is a R. hirta cultivar and is best treated as an annual — purchase or start from fresh seed each year. The species can overwinter in sheltered positions in milder zones, and self-seeded offspring may appear, but those plants will not be genetically identical to the parent. For a perennial rudbeckia with reliable colour longevity, choose an R. fulgida variety instead.
Why does R. laciniata spread so aggressively?
R. laciniata spreads by underground rhizomes in a way that can outcompete neighbouring plants in smaller gardens. Unlike R. fulgida, which spreads slowly and stays contained, R. laciniata can colonise large areas relatively quickly. In formal borders, annual division or root barriers keep it manageable. In a large naturalistic garden or meadow, its vigour becomes an asset rather than a problem.
What is the best rudbeckia for a small garden?
Little Goldstar (R. fulgida var. sullivantii, ~20 inches) is the best choice for a true perennial in a small space. Denver Daisy and Cappuccino (~17–24 inches, R. hirta types) work if you are happy to replace plants annually. Avoid R. laciniata cultivars in small gardens — they will take over.
