A megaherb is a really big plant that can grow up to 6 meters tall! These kinds of plants usually live in places with dry climates, like deserts or very sunny areas. They are adapted to these conditions in order to conserve water and keep themselves alive. Megaherbs also have very large, deep roots so that they can draw water out of the ground and use it to survive. Most of these plants have wonderful flowers and large, vibrant leaves that make them stand out in their natural environment.
