This spectacular perennial hybrid has 18-inch-tall spires of buttery yellow flowers in late spring and beautiful blue-green foliage throughout summer. Tough, exceptionally drought tolerant, and extremely long-lived, it's the southern substitute for the much sought-after lupine. 'Carolina Moonlight' has an adaptable, easy-to-grow nature and makes a great companion for other rugged plants such as ornamental grasses.

Yellow flag is a vigorous Laevigata iris with ribbed, sword-shaped gray-green leaves. It grows to 3 to 4 feet high. Over 60 cultivars exist, including ‘Beuron’, with evenly yellow flowers; ‘Ecru’, with its off-white blooms; ‘Fresh Cream’, with lovely, pale-yellow flowers marked with red-violet signals; a variegated type, ‘Variegata’; ‘Donau’, a bright-yellow flower adorned with a brown signal that looks like stitchery; and nearly sterile ‘Holden Clough’, with deep-yellow blooms and reddish purple veining.

This erect perennial has basal rosettes and stems bearing lance-shaped mid-green leaves. The plant bears long panicles of scarlet or yellow flowers from early summer to early autumn.

In early autumn, this species produces elegant, wand-shaped flowerheads atop wiry stems with blue-green, linear leaves. It is found in open woods and along woodland edges, and prefers some shade. It responds well to rich soil, but can tolerate dry soil also. 

This species has open, tree-shaped flower clusters that radiate out like a fountain. It has given rise to S. rugosa 'Fireworks'.  It can grow to 7 feet tall and blooms in mid- to late autumn.
