  • Description & Ethnobotany
    • Plant Morphology :
      Growth Form: Herb with creeping growth habit.
      Foliage: Bipinnate leaves are composed of about 5 oblong pinnae. Each pinnae is made up of  15 - 20 pairs of oblong pinnules (0.5 cm long). The leaves fold and bend at night and upon being touched. A gentle touch will cause only the pairs of pinnules to fold, whereas a forceful touch will cause the entire leaf to droop from the base of the petiole. Leaves that have been stimulated to fold by touching require about 30 minutes to unfold. The touch-induced leaf movements may be an adaptation to deter herbivores.
      Flowers: Pompom-shaped flowers (0.5 - 1 cm wide) are composed of hundred of thin strand-like petals. Small clusted or 5 - 8 flowers are borne in the leaf axils.
      Cultivation :
      Although this species is often considered a weed in Singapore, it is sometimes grown in containers for its interesting ability to fold its leaves when touched. It should be planted in fertile, well-drained soil that is kept moist. Feed plants weekly with a half-strength, balanced fertilizer. Plants grow and flower best when slight rootbound, but re-pot them when roots have emerged from the drainage holes. Plants become unsightly after about a year, and new plants should be started if desired. Propagate by seeds.
      Etymology :
      The genus "Mimosa" is Greek for mimic, and the specific epithet "pudica" is Latin for shy or shrinking. The genus and specific epithet both refer to how the leaves fold when touched.
      Ethnobotanical Uses :
      Medicinal (A child is bathed in a decoction of the plant or a small branch placed under his pillow whenever there is difficulty in sleeping. Such practices, seen in Malaysia and Indonesia, originated from the 'sleeping' movement of the plant when touched. The pounded leaves are applied to swellings. In the Philippines, the leaves are soaked in coconut oil and placed on wounds and ulcers. It is also used to treat asthma.)
