Cute, but not hot!
When your flowers are pollinated, they produce seeds. You pick these seeds and store them in your seed box, or throw them away in the trash can - which strangely enough gives you a few dollars for the seeds. You find different product upgrades that soon becomes necessary to go on, as the flowers demand better and better soil. I found this a bit annoying at times, since the flowers just kept dying, and it was hard to buy better soil. There are, however, a few tricks that can be used, such as selling the same kind of flower over and over, until you have enough cash. That is, however, extremely boring.
All in all, it really is a waste of time.
