Flower Power!

once you figure out you don't need 2 or 3 in a row to click a flower it becomes... well boring. Make it so they have to be in groups and I could see a game here. Now not so much.

I think you should try taking this in two directions: a puzzle mode with a limited number of clicks to accomplish a specific goal, and an arcade mode similar to what you currently have. (Maybe with dalewj's suggestion)
