How often do you play with PlantSims?

I downloaded custom skins and hair to make plant sims look more like their TS2 counterparts, but don't actually use them all that much because there's nothing special about them. One of my StrangerVille families consists only of plant sims, and I made up a story about them being the Mother's elite minions, but I have yet to actually play with them. Does anyone else have problems with plant sims randomly changing their hair styles, by the way? Because that's yet another reason I don't use them a lot.
