Sensitive Plant (Mimosa pudica): The Touch-Reactive Houseplant

Botanical Name: Mimosa pudica

It won't giggle like Elmo, but Sensitive Plant has a big reaction to touch. Leaves fold up instantly—and entire stems collapse—when tickled, making it fascinating to watch.

Leaves also close at night, reopening in morning. They fold if shaken or exposed to heat (75–85°F/24–29°C may trigger closure). Recovery takes just minutes.

Feathery fern-like leaves comprise 25 pairs of tiny leaflets. Attractive foliage plus profuse pink pompon flowers summer through fall.

M. pudica is a perennial shrub but often treated as annual—it deteriorates after flowering. Younger plants are prettier; seed is quick/easy to grow.

Put outside for summer light if desired, but don't plant in garden—invasive in warm climates, spreads like a weed.

Buying Tip
