All plants need water to survive, although some get moisture from the air and don’t need direct watering.
I guess some plants can survive without water like the plants I see on the streets or just at the forest.
All of the plants still needs water. The ones you see still absorbs water from the rain.
I get it now. They still grow or live even weeks without rain maybe?
You are right. With too much exposure from sun without water for how many weeks, the leaves will dry and also roots might be rotten.
