This pollen-free sunflower branches freely and grows to a height of 4 to 6 feet. Pollen-free sunflowers were produced as this quality meant even allergic people could have a bouquet of sunflowers on their table, another plus is no unsightly pollen dropping onto the table. This flower will still produce seeds if pollinated by a pollen-carrying bee or insect. Extremely dark in color, the burgundy red petals become almost black close to the disc. A unique focal point in any garden. Flowers are quite large, 6-8 inches across, and stems are long enough for cutting. (F1)
