Mimosa pudica “Touchy Tina” – The Sensitive and Fascinating Tropical Herb

Mimosa pudica, better known as Touchy Tina, Shy Plant, or Sleeping Plant, is a unique tropical plant admired worldwide for its remarkable sensitivity to touch. It's a versatile and playful plant that offers both decorative and educational value in the home, garden, or office.

What is Mimosa pudica?

Mimosa pudica belongs to the legume family (Fabaceae) and is native to South and Central America. The plant is a fast-growing, low-growing shrub with delicate, light green leaves that immediately close when touched—a phenomenon known as thigmonasty. This conspicuous behavior serves as a natural defense mechanism against herbivores.

Touchy Tina is a popular cultivar of Mimosa pudica known for its compact growth, delicate leaves, and quick response to touch. In addition to the leaves, the plant produces small, round, pink flowers that add an attractive decorative touch.

• Leaves: Light green, pinnate and very sensitive; they close when touched or at dusk.

• Stems: Flexible and slightly hairy, suitable for pots and container cultivation.

• Flowers: Small, round, pink flowers that bloom in summer and enhance the plant's tropical charm.

• Behavior: The plant's "touchy" nature makes it an educational and playful plant for children and adults.
