The Plant and its Environment
The pumkin grows in warmer climes and is an ancient vegetable (fruit). It is said to have grown continuously in the Americas for some 9,000 to 10, 000 years! Pumpkins were introduced into England in the 17th Century where they grow quite well on compost heaps, and these huge vegetables captured the popular imagination, even to the extent of being incorporated in a fairy tale. Pumpkin pie is popular in the USA and the hollowed out shell with candlelight shining through the pierced eyes and mouth is ubiquitous at Halloween.
Method of Extraction
The seeds are pressed to make a dark sweetish oil.
