The castor tree: 

The castor tree (Ricinus) is originally native in the tropics, in India or Africa. Today castor trees are growing as ornamental and agricultural trees in many countries. The castor tree reaches a climate-dependent height of 1 to 2 m in the temperate zones and up to 13 m in the tropics. The strain is blue frosted-branched with a greenish to reddish colour. The leaves are up to 1 m in width, resemble a spread hand, and always have the same colour as the trunk. They have a long stalk, are 5 to 11-times toothed at the leaf edge and are growing in alternate positions. The male flowers grow in clusters. They are below the terminally stalked female flowers and are often overlapped by the side shoots. The fruits are bright red, up to 2.5 cm in diameter and have spines. The fruits contain three seeds, which are bean shaped in form and size.

How castor oil FSG is produced:

Organic castor seed oil is typically produced by cold pressing from the peeled seeds. This product is called castor oil First Special Grade (FSG) because it is from the first pressing. The oil has a slightly yellowish color.
