PlantFiles: Small leaf Sensitive Plant Sensitive Plant
Neptunia aquatica

I have this in my aquarium by the window and it opens and closes in the sunlight. Very cool plant. Got it the other day and it's already got a new sprout!

Really cool plant. Can either be potted or floated on the surface. I placed this plant in my pond and about 20 minutes later the leaves were open and ready for buisness. It's really cool to touch the leaves and watch them close. These are great for ponds where children visit but also equilly fun for those of all ages. I certainly have fun playing with them. However these being tropical means I'll have to setup an aquarium this winter. Oh well that means I'll be closer and have more time with them.

The sensitive plant is one of the only plants to have a simple nervous system,they grow as weeds in tropical climates,the leaves close up when touched, cold or in the dark, in spring it produces a pink fluffy flower ball
