Swamp Sunflower
Helianthus angustifolius
Fields of sunshine may be the best way to describe the beautiful blooms of this prolific perennial. You will need to give
this plant, one of the first flowers of fall, a bit of room. A single plant can grow up to 12 feet tall and 4 feet wide. Place
it toward the back of your perennial or shrub border in a sunny location. It can take average soil that’s moist. Selections
such as ‘Gold Lace’ grow smaller, around 5 feet tall and wide. ‘Mellow Yellow’ offers pale yellow blossoms on a plant around
9 feet tall and 4 feet wide. An added bonus: Butterflies and birds love this plant.
Editor’s tip: You can control the size by simply cutting it back by half in midsummer. It will then grow, set flowerbuds, and stay a more
reasonable size when it blooms in your fall border. Swamp sunflowers grow in the Upper, Middle, Lower, and Coastal South.
