There are quite a bit of plants- but I know there are those mandrakes- the ones that scream REAL loud- featured in the Chamber of Secrets and of course the Devil's Snare- you have to relax and it'll let you go, feautured in The Philosophers Stone. There probably are more- but I don't go to Hogwarts so... hope I helped a bit anyway.

Mandrakes are a plant that helps restore those who have been petrified to their original state. Their cry is also fatal to those who hear it. Mandrakes were first introduced in the book Harry Potter and the Chamber of Secrets, and then are mentioned briefly in Harry Potter and the Deathly Hallows.
Harry, ron, and Hermione fall into devils snare. A plant that strangles youth more you struggle.
