Did you Know?
The stunning and geometric Rattlesnake Plant (Goeppertia insignis) on this list of plants that start with R has a clever daily routine that makes it look alive! The base of each long, wavy leaf has a tiny joint that reacts to changing light levels. As the sun sets, the plant lowers water pressure in this joint, causing the leaves to fold straight up like hands in prayer. This exposes the deep purple leaf undersides for the night, resetting automatically at sunrise!
