Harxhem is a winegrowing village on Mainz’s southern outskirts.

It belongs to the Verbandsgemeinde of Bodenheim, whose seat is in the like-named municipality.

[citation needed] The council is made up of 16 council members, counting the part-time mayor, with seats apportioned thus: (as at municipal election held on 25 May 2014) The municipality's arms might be described thus: Or an oak sprig slipped in chief dexter acorned of two, the acorns per pale in chief and per pale reversed in base, the whole in bend, and an ear of grain slipped, the head in chief sinister, per bend sinister, all vert, the whole surmounted by a bunch of grapes azure slipped of the second, with the stem twisted round upon itself.

The German blazon states that the first two charges, the oak sprig and the ear of grain, are to be vert (green), although the latter is not shown here in that tincture, but in something that might be blazoned “proper” (that is, in natural colours).
