Strong Growth And Branching Habit, Earlier To Bloom Than Other Sunflowers, Amazing Flowers In Either Red Or Brown Tones.

If kept away from late afternoon sun this sunflower will stay darker. When first open the colour is as close to black as I have seen in a sunflower especially in a plant with red tones but the brown toned ones dont seem to get as dark. This sunflower is excellent for cutting and is one of my favourites for its growth and beauty.
