Sunflower, Mexican (Tithonia)

Sunflowers are incredibly easy to grow from seed. Plant the seeds in very late spring when the ground has warmed considerably. Moisten the soil and keep slightly moist until germination. For continuous blooms, start a second group of seeds in mid-summer. These plants will bloom in September and October.

Sunflower, Mexican (Tithonia)

The Tithonia, also known as The Mexican Sunflower is a member of the Daisy family and native to Mexico and Central America where it grows in the brush or among the scrubby grasses at the sides of roads or forests. Spanish explorers discovered the plant during their early excursions into Mexico and brought it back to Europe in the 1500’s. By the 1700’s it was being grown in the United States and Thomas Jefferson had included it in his Monticello gardens. In the wild, the plant grows to 6 or more feet on stems which can be hairy. It produces orange-yellow, daisy-like flowerheads. The cultivated plant grows to a height of 3-6 feet and produces large, deep orange to rust colored blossoms that are 3-4 inches in diameter. The flowers resemble single layered dahlias. The flowers make excellent cut flowers usually lasting for well over a week. The plants are known to produce prolifically if they are routinely deadheaded.
