Facts about Sunflowers

The name sunflower comes from the Greek helios "sun" and anthos "flower." Sunflower got its name because the flowers turn toward the sun. Some kinds of sunflowers are grown for food, seeds and oil. A sunflower head can produce up to 1,000 seeds.

Seed heads – Annual sunflowers can have either large or small seed heads, but perennial sunflowers have only small seed heads. Blooms – Annual sunflowers will bloom the first year after being planted from seeds, but perennial sunflowers grown from seed will not bloom for at least two years.Mar 17, 2015

Re-Blooming. Sunflowers grown as annuals die after producing their flower heads go to seed. They do not grow and bloom again. These are usually the varieties cultivated for their large size, showy flower heads and edible seeds.
