His location on the map is deceptive, but that is where he's located on the surface. Stays under the ground looking like a flower until he is aggroed like most stemdragons. He hits about the same as most rares ~2-3k at 9000 armor. He has an instant fairly long duration stun, so saving a CC break is helpful. Probably the most dangerous move is the Spore Bomb which was hitting me for over 10k. Fairly easy solo as an engineer if you don't get spore bombed.
