Joker Sunflower is a hybrid, pollenless sunflower variety that is the perfect “wild card” for your garden. This variety has a unique, double starburst pattern on large, 6-8″ blooms. Joker works great for attracting pollinators to the vegetable garden, but is also ideal for cut-flower bouquets because the blooms are pollen-free. Plants grow to 6-7′ tall, which makes this a great option for a border plant around the garden. Joker Sunflower plants are branching and will continue to produce additional blooms throughout the growing season. The large flower heads have a fuzzy, brown disk in the center with a slight yellow fringe surrounding the disk. The petals have a maroon center and are tipped with yellow to provide a fabulous, eye-catching appearance.
Joker Sunflower can be direct-seeded or transplanted. Direct-seeding can be easily done with a walk-behind planter like our Hoss Garden Seeder. We recommend using a #3 seed plate and modifying the hole size to fit the variety being planted. Sunflower seed size can vary greatly from one variety to the next, therefore it’s important to always calibrate the seed plate hole size for the variety being planted. Sunflowers grow well when planted on double rows with drip irrigation. Lay one row of drip tape and plant on both sides of the tape to maximize garden space. Sunflowers also perform well when transplanted. They grow great in our heavy-duty seed starting trays. Transplants are ready to go in the ground when plants can be easily pulled from the seed starting trays. For increased storage potential, harvest sunflowers when blooms are closed. Blooms will then open when cut and placed into a container with water.
