Tall varieties may need staking. Promptly deadhead spent flowers as flower heads are heavy and can cause stems to snap. Tolerates clay and dry soil but prefers moist, well-drained soil. Tolerates full sun but appreciates some light afternoon shade. Leaves and flowers are fragrant when brushed or crushed. Pinch young plants to promote bushy growth.
Triploid F1 hybrids (T. erecta x T. patula) combine the large flowers of the African marigold with the more compact size of the French marigold into vigorous plants featuring 2-3” diameter flowers on stems rising 10-18” tall. These triploids seem unaffected by high summer heat and generally bloom throughout the summer.
