Mimosa Pudica aka Sensitive Plant aka Tickle Me Plant, folds up its leaves when touched. So another of its names is Touch Me Not plant. It also folds up its leaves at night but for some reason it doesn't have the name Folds Up Its Leaves At Night plant. Go figure.
We all know plants are alive but have you ever seen one move unless the wind was blowing? This one will fold up its leaves and stems if disturbed. This is a fast and immediate reaction which makes it seem sentient. I bought one for my sister once. It has delicate, fluffy, pinkish-purple flower balls and is so common it is thought of as a weed in its native land. She called it "Wincey" because it winces. It also has spikes. Which are exposed when the plant folds up. Which makes it a violent sleeper type. Wincey like a cactus, I'd say.
...delicate pom pom flowers...
...pretty! It lulls you with its delicate beauty and then
impales you with its spikes of death
