19-3-2025 , OLD CITY POLONNARUW, SRI LANKA - SENSITIVE PLANT (Mimosa pudica)

Mimosa pudica (also called sensitive plant, sleepy grass,[citation needed] sleepy plant, action plant, humble plant, touch-me-not, touch-and-die, or shameplant) is a creeping annual or perennial flowering plant of the pea/legume family Fabaceae. It is often grown for its curiosity value: the sensitive compound leaves quickly fold inward and droop when touched or shaken and re-open a few minutes later. For this reason, this species is commonly cited as an example of rapid plant movement. Like a number of other plant species, it undergoes changes in leaf orientation termed "sleep" or nyctinastic movement. The foliage closes during darkness and reopens in light. This was first studied by French scientist Jean-Jacques d'Ortous. In the UK it has gained the Royal Horticultural Society's Award of Garden Merit.

The species is native to the Caribbean and South and Central America, but is now a pantropical weed, and can now be found in the Southern United States, South Asia, East Asia, Micronesia, Australia, South Africa, and West Africa as well. It is not shade-tolerant and is primarily found on soils with low nutrient concentrations.

28-5-2023 TABIN RESERVE, BORNEO - SENSITIVE PLANT (Mimosa pudica)


Mimosa pudica (from Latin pudica 'shy, bashful, or shrinking'; also called sensitive plant, sleepy plant, action plant, touch-me-not, or shameplant is a creeping annual or perennial flowering plant of the pea/legume family Fabaceae.

The species is native to the Caribbean and South and Central America, but is now a pantropical weed, and can now be found in the Southern United States, South Asia, East Asia, Micronesia, Australia, South Africa, and West Africa as well. It is not shade-tolerant and is primarily found on soils with low nutrient concentrations.

Mimosa pudica is well known for its rapid plant movement. Like a number of other plant species, it undergoes changes in leaf orientation termed "sleep" or nyctinastic movement. The foliage closes during darkness and reopens in light. This was first studied by French scientist Jean-Jacques d'Ortous de Mairan. Due to Mimosa's unique response to touch, it became an ideal plant for many experiments regarding plant habituation and memory.
