do plants grow better when its hot or cold?

Well when I did an experiment, I found out that the hot climate grew shorter but it bloomed better than the cold one. While the cold one grew taller , but it wither. So, I think it will grow better in between.

Well, if you've ever noticed, when it gets COLD outside, the plants drop their leaves, freeze, and die. On the other hand, when it gets too hot, plants have do water and they dry up. So let's use our brain here. You probably want a temperature somewhere in-between.
