Mimosa is a sensitive and an unusual greenhouse or house plant. The children will love it as the leaves fold up when the leaves are touched. When the attractive, finely cut leaflets are touched or otherwise disturbed, the leaves and branched will drop and fold up with astonishing speed and quickly expand again. Leaves fold up at night. They need an indoor area of full sunlight and you need to be careful do not over watering it. With the mimosa seeds the plant will produce small “silk tree” blossoms.
