This wild and naturally occurring yellow multi- branched sunflower grows to an average height between 122-182 cm (4-6’) tall and produces a surprisingly amount of bright yellow blooms with chocolate brown centers per plant. Blooms are between 7-15 cm (3-5”) across. Blooms all summer long until the fall frost. Strong branches and small blooms make it an ideal candidate for small bouquets.
