Just a relaxing sandbox to cool your heels in between bouts of simulated violence on pixels.
For those who need a little color and zen in their lives, it's a great addition to your library for a small price.
My only "complaint" would be that the game needs more plants to choose from.
In any case, if you're looking for a change of pace and you are flower-challenged in the real world, it's a good little game to spend time with.
