Thank you for telling me about the berry.
I've had the game downloaded for more than a day now, and have played for almost 12 in game hours, and no berries have sprouted, though I have been watering them. To be extra sure, I also messed around with my computer's internal clock. Moving it forward six hours, 12 hours, 24 hours, a week, a month. The day night cycle shifted with my computer's internal clock, but berries never grew.
So I think they just won't?
