Mimosa somnians is notable for exhibiting rapid plant movement. Its leaves are sensitive to tactile stimulus, folding quickly when touched, similar to Mimosa pudica.[4] It can be differentiated from Mimosa pudica in that its leaves are bipinnate, there are more than four subbranchlets and these originate from more than one point on the branch.[4]
Mimosa somnians's leaflets are 4–5 mm long.[3] The flowers form pink balls.[3] It propagates by seeds.[4]
