There are so many out of this list. Grapeshot, Imitater, Power Lily, Primal Sunflower, Gold Bloom.

Also Primal Peashooter is great, however there are some zombies that practically negate it.

Also I've never seen someone use Cactus outside of La Brainsa Tarpits because of it's slight Ankylosaurus counter.
