Description
Chrysanthemum-like Blooms for Glorious Summer Borders
The sunflower 'Tall Sungold' (Helianthus annuus) is an especially attractive, double-flowered variety with fluffy, densely packed petals in a warm golden-yellow hue. Unlike the classic sunflower, it has no dark centre, but displays a soft, fully yellow core – almost like a plush garden chrysanthemum.
Reaching a height of 150–180?cm, it ranks among the taller sunflowers, yet remains remarkably sturdy. Its branching habit produces multiple blooms per plant – perfect for flowering screens, informal summer hedges, or large planting beds.
Despite its double form, 'Tall Sungold' is pollinator-friendly, offering valuable forage for wild bees and other beneficial insects. Its large, soft blooms also make superb cut flowers for bold and expressive arrangements.
