Around 7,500 varieties of this fruit are grown throughout the world (100 varieties are grown commercially in the US). The peel of the apple contains about two-thirds of the fiber and the majority of the phytonutrients. The apple tree originated between the Caspian Sea and the Black Sea. Apples are grown in all 50 states and they come in all shades of red, green, and yellow.

Seed stratification is necessary before planting apple seeds. Place seeds in a moist paper towel, place inside a plastic bag, and then store seeds in the refrigerator for 6 to 8 weeks. Leave a small opening in the plastic bag for air flow. Check the plastic bag weekly to make sure it stays moist. Once seeds are stratified, they can be sprouted in a pot and later transplanted, or they can be sewn directly into the soil.
