The Sensitive Plant

The sensitive plant is one of the many names of memosa pudica, putica being latin for chaste or modest, shamefaced or bashful. It's a spiny little shrub that grows up to about a foot off the ground and has these pink flower puffs with compound leaves. To see the the sensitive plant in action, all you need to do is touch a finger on one of branches, and suddenly what happens is the leaflets all fold inward like a closing suit case.
