Create a floral hedge with a mix of striking sunflowers! Plants grow 6-7' tall and display golden, red bicolor and yellow flowers with dark centers. Sunflowers grow best in locations with full sun and can withstand some drought. It is easiest to sow seeds directly into the soil after all danger of spring frost is past.
