Pomegranites not growing from cherry/apple grafted trees?

Oh yes, I forgot you can get stuff from the festivals. Well, all those annoying pop-ups that I keep ignoring might have been what I was looking for all along. Won't be so fast to dismiss them next time I see them. Luckily ghosts don't age so they will wait till my living sim gets the ambrosia made (I do cheat with my living sims and de-age the ones I like and keep them young...the rest of the neighborhood is on it's own though).
