Did you know, sunflowers originated in North America,
and were used by the Natives of Central and North
America to make oil. It was introduced to Europe in
the 1500's.
The seeds of the sunflower are rich in protein, and
they produce a high quality oil which is often used to
make margarine and cooking oil. Sunflowers can grow as
high as 15 feet. There are also dwarf sunflower plants
that will only grow 2-3 feet tall, too.
One sunflower head can produce up to 1,000 seeds!
The sunflower is the state flower of Kansas.
A sunflower is ready to harvest when the back portion
of the head turns brown.
There are 50 species and 19 subspecies of sunflowers
found in the United States.
