Sunflower ‘Formula’
Botanical Name: Helianthus annuus
Type: Half-Hardy Annual

Sunflower ‘Formula’ is a compact, multi-branching variety that produces a profusion of medium-sized golden blooms with classic dark centres. Unlike tall single-stem types, ‘Formula’ forms a bushy plant with multiple flower heads, making it perfect for borders, containers, and cutting gardens. Long-lasting, pollen-rich, and attractive to bees and butterflies, this variety brings season-long colour and pollinator action to any sunny space.
