These branching plants with thick stems and glossy mid-green leaves grow 5 to 6 feet tall. Slightly nodding flowerheads 2.5 inches or more across appear in summer. Bright yellow ray florets are sometimes flushed with red or purple-red disk florets.
Noteworthy CharacteristicsCultivars include ‘Italian White’, a graceful plant with 4-inch ivory-white daisies shading to buttery cream near their striking black centers; ‘Lemon Queen’, a pale yellow cultivar accented by a large brown center; ‘Velvet Queen’, well branched from a strong stalk, with dark burgundy petals and a black central disk; ‘Sole d’Oro’, a double-flowering form with a fluffy butter-yellow head; and ‘Stella’, a branching plant with golden petals and a maroon center.
CareTall cultivars may require support. Needs long, hot summers to flower well. Grow in moist but well-drained, moderately fertile, humus-rich soil.
