Touch me not /Chui Mui Plant in 4 inch poly bag

The “Touch-me-not plant” is commonly the plant species Mimosa pudica.

Why it’s called “touch-me-not”

Its leaves fold inward quickly when touched, shaken, or exposed to heat. This movement is called thigmonasty (a touch response).

Key features

• Leaves: Small, feathery, and fold up on touch
• Flowers: Small, round, pink/purple puff-like blooms
• Stem: Low-growing, slightly prickly
• Habit: Creeping plant, spreads along the ground
• Reaction speed: Leaves can close in seconds and reopen later

How it works (simple explanation)

Inside the leaf joints are cells filled with water pressure. When the plant is touched, it quickly moves water out of those cells → the leaf loses stiffness and folds.

Why it does this

Scientists think it may help:

• Protect against herbivores (looks “dead” or less attractive)
• Shake off insects or rain droplets
• Reduce damage from environmental stress

Interesting fact

Even without being touched, it can close at night and reopen in daylight (a natural sleep-like rhythm).

If you want, I can also explain how to grow it at home or why it’s used in school science experiments.
