Sunflowers are native(pärit) to the Americas. The earliest known examples of a fully
domesticated sunflower were found at the Olmec site of San Andrés dating some time
before 2500 B.C.[1] The Incas used the sunflower as an image of their sun god. Gold
images of the flower, as well as seeds, were taken back to Europe early in the 16th
century.
The Giant sunflower (Hlianthus giganteus) is native to Connecticut. They can grow to be
between 3 and 12 feet tall. Their flower heads can be between 2 to 3 inches wide. They
are most commonly found in valleys with wet meadows or swamps. The Giant sunflower
grows between July and October.
To grow well, sunflowers need full sun. They grow best in fertile, moist, well-drained
soil with a lot of mulch. In commercial planting, seeds are planted 45 cm (1.5') apart and
2.5 cm (1") deep.
