Flowers in Farmville are just like any other crop. You sell them, gain XP for growing them and can master them by growing enough of them. But in addition while harvesting there is a chance that you will pick a perfect bunch. If you have a Garden Shed that perfect bunch will be available to use as decorations for your Farm(They last 14 days after you use them not from the point at which you find them.). You can also choose to share them with your friends. You set how many you want to share and then post a note to your news feed. Anybody who clicks on it will get an arrangement for their farm. The Garden Shed can be purchased from the store. You can only have a single Garden shed which has a store amount of 30 bunches. These bunches can be any mix of available flowers but you can only store 30
