Re: What is your most UNUSED plant?
There are so many useless plants that it's hard to pick just one.
If i had to pick one I'd go for e.m. peach.
But rotobaga, intensive carrot, garlic (used a lot in first pvz), shadow-shroom, celery stalker, perfume-shroom and electric current (i can't believe i bought that) would all make the shortlist.
Single sun, peashooter and potato mine (primal potato mine vastly superior) quickly became redundant.
