It means plain.

Sharan presumably comes from Sharon, which is an Old Testament place name. In Hebrew שָׁרוֹן (Sharon), meaning "plain", is referring to the fertile plain near the coast of Israel. Additionally, it is also the name of a type of flowering shrub, the Rose of Sharon.

Sharon (שרון) means "plain" (as an a field) or "fertile land". It also refers to a place in Israel.

It is mentioned in the Bible as a synonym for something Fair and Good- the Rose of Sharon, evidentally a flower. This is the name of one of the characters in the Joad Family of (Grapes of Wrath) and in a sense the youngest daughter.
The word Sharon is Hebrew for 'plain' as in a flat area of land. There is a Plain of Sharon in Israel, and the Rose of Sharon comes from there.
