I cannot speak on behalf of the grays, but my Whites are a whirling dervish of destruction. I started with 8 real plants and no fake plants. Now I have 1 real and like 4 fake. Its those cursed teenage years (months for them) they never listen, they think they know everything and they are so destructive! Ok maybe not that bad. The only plant of mine that has stood the trials of the frogs is my mother in law tongue plant, I am thinking about getting a few more of these for this reason!
