The shea nut tree grows in the Savanna Grassland on the west coast of Africa. Millions of shea nut trees, which grow to about 60 feet tall, are harvested in the raining season during the months of May through August. The fruit is very delicious. The shea nut seeds are collected and usually sun dried. At the end of the season when the nuts are well cured and dried, they are threshed and picked to separate the white nuts from the yellow nuts.
