Sunfinity® Double Yellow Sunflower (Helianthus annuus) showcases generous layers of golden petals from late spring until frost. Our growing trials confirm that it keeps producing fresh blooms even in demanding conditions. It reaches around 3 to 4 feet in height and adds a commanding presence wherever it's planted. Many gardeners favor its extended blooming season over typical sunflowers for consistent, cheery color.

'Sunfinity® Double Yellow' has a branching habit that supports a steady supply of new blooms, and it rarely demands constant upkeep. This annual flower, native to North America, tolerates heat well and often resists common pests. It fits mass plantings, borders, or containers, bringing a warm focal point to outdoor spaces. Pollinators appreciate its nectar-rich centers, which can help support a thriving garden ecosystem.

Sunfinity® Double Yellow Sunflower Care

Position it in full sun with well-draining soil, and blend compost at planting time if needed. Water regularly, but avoid overwatering, as roots prefer moderate moisture without sogginess. A balanced fertilizer applied every few weeks promotes healthy growth and consistent buds. Slightly acidic to neutral soil pH often gives the best results.

Prune spent flower heads if you like a tidier appearance, though some gardeners leave them as a food source for birds. Pinch or thin early stems to encourage branching and control height, especially in smaller beds. Container-grown plants should be checked for dryness more often, and they may require supplemental support if stems get heavy with blooms. In regions with mild winters, you can remove the plant when it finishes its seasonal cycle or try to overwinter in a protected spot. 

Sunfinity® Double Yellow Sunflower Spacing

Allow about 18 to 24 inches between plants for rows or mass plantings to maintain air circulation and access for pollinators. Single specimens or border plantings can manage with slightly tighter spacing if you plan to prune or stake. Choose a container at least 12 inches wide for a new planting, with larger pots offering steadier moisture levels. Sufficient space encourages robust root development and better overall performance.
