I wondered the same thing but it seems as those that red/blue fruit is just pretty artwork, and doesn't represent another type of seed. I do wish that we could have had more trees in the orchard. It seems like at least two more trees could have fit in that space. Still, I'm thrilled we got a lovely orchard in this game instead of another boring farm crop, and I'm selfishly hoping the next game will have a pretty orchard too!
