What's it's full moveset? Mine has Spore, seed bomb, x-scissor (both STABS) and aromatherapy. It can learn stun spore by level, not a bad move. Swords dance could be ok if you plan to sweep, but it's really slow... Brick break for coverage (to hit all things that resists it's STAB moves). Can get sinthesys by move tutor, as well as knock off.
It's movepool is not huge, but it has some decent options.
I really like parasect ^^
