Well, if the plants that the creator has already made don't give enough inspiration. There is a monster girl h-game with its own wikia that I know of. You might be able to get some ideas from that.

Only fair to warn you though, these monster go a bit too far with the men they catch, so you might want to take a more moderate approach if you do use them.

The link for the wikia is here and the category page for plant monsters is here.
