Singhara Plant

Singhara Plant, also popular as Indian Water chestnut or Water Caltrop in English, is an aquatic plant with a rough, thick-skin enclosing white flesh. This plant grows in a mat-like formation, with upper leaves floating on the surface while the lower ones remain submerged. More than two-thirds of the plant remains submerged in the water. This plant usually grows in ponds, marshes, and lakes and requires full sunlight with rich organic content.

After pollination, the plant submerges itself so that the fruit can develop. When mature, the fruits drop off in the water, where a net is used to collect them.

Botanical Name: Trapa natans
