Double Sunking is a fully double sunflower that transforms the classic summer bloom into something theatrical and lush. Growing to 6 feet tall, it produces plush, soft, fluffy golden heads packed with petals rather than a traditional center disk. This heirloom annual thrives in zones 2-11 and matures in 80-100 days, making it an exceptional choice for cutting gardens and floral design. The dramatically lower pollen count and exceptional vase life set it apart from standard sunflowers, allowing you to bring armfuls of these cheerful giants indoors without the mess.

The standout feature here is the fully double form itself, a bloom so densely packed with petals that it barely resembles a conventional sunflower. At 6 feet tall with those plush golden heads, Double Sunking commands attention in any garden or vase. The extra-long vase life and dramatically reduced pollen make this the rare sunflower that actually improves your home when cut, rather than dropping pollen on every surface. For anyone serious about cutting gardens, this variety stops being optional.
Double Sunking is grown specifically for cutting and floral design. The fully double blooms, combined with their height and exceptional vase life, make them the florist's choice among sunflower varieties. The low pollen count means these flowers can be brought indoors without the yellow dust that typically comes with sunflowers, making them suitable for arrangements in homes and spaces where allergies or cleanliness are concerns.

Direct sow seeds 1/2 inch deep into warm soil after the last frost date. Seeds germinate in 7-14 days when soil temperatures are between 50-75°F. For the fastest germination, wait until soil reaches 65-75°F.
Cut stems for arrangements when the fully double blooms are fully open and petals feel plush to the touch, typically around 80-100 days after sowing. Harvest in early morning when stems are most turgid, cutting stems as long as possible with sharp pruners. The reduced pollen means these blooms are safe to bring indoors immediately. For longest vase life, cut just as the bloom reaches full double form rather than waiting for over-maturity.
