Although a shorter version of the straight species, at nearly 6 feet tall, ‘Gold Standard’ is still a large and lofty plant with strong stems and upright blue-green foliage that yield a bounty of bright and fragrant lemon-yellow daisies in late summer. This shorter form of C. tripteris not only produces more flowers, but also has an extended bloom period of up to 6 weeks. Extremely disease resistant, ‘Gold Standard’ prefers to grow in full sun and dry to medium well-drained soil. Suggested companion plants include Vernonia (ironweed), Symphyotrichum laeve (smooth blue aster) Schizachyrium scoparium (little bluestem).
