Are you curious about what's inside a seed? Or how a root pushes its way into the soil? Or which flower part is the stamen and which the pistil? Paul Young's The Botany Coloring Book (Harper Perennial, 1982) is a hands-on approach to learning many basics of botany. Adults as well as students will enjoy this multi-sensory approach of reading, identifying, and coloring plant parts.
