Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Each time a face-up Plant-Type monster(s) on the field is destroyed, place 1 Flower Counter on this card. You can remove any number of Flower Counters from this card to activate these effects. ● 1 Counter: Target 1 Plant-Type monster on the field; that target gains 400 ATK and DEF until the end of this turn. (This ATK gain remains even if this card leaves the field.) ● 2 Counters: Target 1 card on the field; destroy that target. ● 3 Counters: Target 1 Plant-Type monster in your Graveyard; Special Summon that target.
