Cotton
Cotton is in the mallow family and produces delicate, lovely flowers.  Other members of the mallow family include hollyhocks and hibiscus, used to brighten gardens all over the world.  The cotton fiber forms around the seeds of the cotton plant. It helps carry the seeds long distances on the wind so the baby plant can grow up far away. Early humans realized that the soft, fluffy fibers might be suitable for textile use and began to breed the plant, selecting for fluffy, easily spun varieties.
