Water caltrop

I lived most of my life in an area where rivers are fast, closer to mountains. And lakes aren't too many. The whole time I've no idea about this plant until I moved to Kyiv, and one day stepped on it accidentally.

Water caltrop

It is a floating aquatic plant with a wide variety of names: buffalo nut, bat nut, devil pod etc. Latin name Trapa natans. It likes slow-moving waters up to 5 m deep and warm temperature.

Now water caltrop spread throughout the world. It is difficult to determine his homeland. However, it is known that in China it was mentioned in manuscripts 3 thousand years ago. Now it grows on the territory of almost all of Eurasia and Africa. And relatively recently he was accidentally brought to North America, where he also got accustomed.

Trapa natans is cultivated in China, Japan, India and many African countries. In central Africa, there is Lake Malawi, which in translation means "water nut housing".

It is used in landscaping, nutrition and medicine.
