it evolves by ancientpower
no, it can only evolve in pearl, diamond or platinum. in those games it evolves into tangrowth when it learns the move ancient power (which it learns on lvl 33, or with a heart scale if your tangala has already passed that lvl).
After you get the National Dex, make Tangela learn Ancientpower at level 33, and then level it up.

you have to trade a tangela and level it up to level 33, when it learns ancient power. then it will evolve. for more info, go to www.serebii.net.
