Savannah Sunset lion's tail (Leonotis ocymifolia 'Savannah Sunset') produces bright orange, fuzzy, tubular flowers in whorls from mid-summer through fall. A native of Africa, this plant is not hardy in the Chicago area, but it will provide a colorful annual display if planted in full sun and not overwatered. The flowering stems reach 6 feet in height and the plant will grow to 3 feet in width, so a position at the back of the flower bed or border is most appropriate. The leaves are fragrant when crushed.
