Concert Bell sunflower brings big drama to the garden with its unique, vertical display of bright golden blooms. This AAS-winning, branching variety is pollenless and produces multiple clusters of 10 to 12 flowers per stem, creating an impressive tower of color. Each bloom measures about 4 ½ inches across, and plants easily reach 5 feet tall or more. In addition to its showy performance, Concert Bell is remarkably sturdy and stands tall even in stormy weather. A true star that delivers a head-turning display all summer long.
