mimosa


My favourite little pink puff !
That is my favourite one since I was a kid ( 5 or 6 years old.)
Botanical Name: Mimosa Pudica
Common Name: Sensitive Plant , Sleeping Grass , powder puff
When I touch them, they fall asleep.
The leaves fold up when touched. If touched with a bit more force, the petioles will also bend at their pulvinis and the leaves droop. These movements are called seismonastic movements (reaction to physical shock). At night, the leaves will also fold and bend in movements known as nyctonastic movements (reaction to absence of light).
