Tithonia rotundifolia

Mexican Sunflower
Asteraceae (Compositae)
Perennials

Husky, rather coarse plant with velvety green leaves and spectacular gaudy flowers; native from Mexico to Central America. Grows rapidly to 6 ft. tall and 4 ft. wide. Blooms from summer to frost, bearing 3–4-in.-wide blossoms with orange-scarlet rays and tufted yellow centers. Use as a temporary screen. Arcadian Blend grows 2–2 1/2 ft. tall and produces gold, orange, and yellow flowers. ‘Aztec Sun’, to 4 ft. tall, has apricot-gold flowers. ‘Fiesta del Sol’, to 2 1/2 ft. tall, bears 2–3-in. orange flowers and starts blooming earlier than the others. ‘Goldfinger’, a bushy 4-footer with deep orange flowers, makes a good temporary summer hedge. All have hollow stems; cut carefully for bouquets to avoid bending stalks. Sow seeds in place in spring, in well-drained, not-too-rich soil. Tolerates intense heat and some drought.
