The Plant Trivia app touts it as, “a simple game to help you learn 200 plant names and pictures. The game is pretty simple: You start with 60 seconds on the clock. Each correct answer is worth 5 points on the first try, 3 on the second, 2 on the third, and 0 on the last try. When you’re done, save your score and share the results on Facebook.”

Mostly flowers are shown but other plant parts as well.  Sometimes the choices are very different from each other. I did pretty well but my son still has the highest score.  I’m getting rusty or all those field trips with him have paid off! – Steve Young
