By Vicki Gee-Treft A national 2022 All America Selections’ (AAS) Ornamental Winner, Concert Bell puts on quite a performance with multiple clusters of 10 to 12 golden yellow, 5 to 6-inch sunflowers on a 5 to 6 feet columnar stem. Excellent seed germination at 70 degrees makes this beauty very easy to grow. Spacing is recommended at 13 to15 inches to enjoy flower clusters from the top to the middle. For continual summer to fall blooms, direct-sow every 3 weeks after the last frost date in well-drained soil in good sunlight.
AAS judges were very complimentary: “Tall vigorous and uniform plants terminated with one 5-6” wide main bloom surrounded by 3-4” wide side blooms.” “Novel blooming habit. A sunflower bouquet on a single stalk!”
