A stiff, erect plant which features yellow, plate-like, dense, terminal flower clusters (corymbs) up to 5" across and elegant, deeply-cut, fern-like, gray-green leaves. Foliage has a spicy odor when crushed. Good cut or dried flower. Tolerant of summer heat and humidity. Drought tolerant once established. This cultivar is considered a rebloomer and may repeat bloom until frost if faded blooms are promptly removed.
