Types of Water caltrop

Water caltrop, scientifically known as Trapa natans, is a fascinating aquatic plant that has been cultivated for centuries across various parts of the world. This unique plant, often mistaken for a nut due to its edible fruit, actually belongs to the family Trapaceae. Water caltrop comes in several varieties, each with its own distinct characteristics and growing preferences. From the European water caltrop to the Asian varieties, these plants have adapted to different climates and ecosystems, resulting in a diverse range of forms. In this article, we’ll explore the different varieties of water caltrop, highlighting their unique features, native habitats, and culinary uses. Whether you’re a botany enthusiast or simply curious about this intriguing aquatic plant, join us as we dive into the world of water caltrop varieties.

1. Trapa natans var. natans

Trapa natans var. natans, commonly referred to as the European water caltrop, is native to the temperate regions of Europe. This variety is characterized by its distinctive floating leaves, which form rosettes on the water’s surface. The leaves are glossy on top and have a triangular or diamond shape with saw-toothed edges. This variety is well-suited to temperate climates and is often found in slow-moving bodies of fresh water such as ponds, lakes, and dams. Unfortunately, Trapa natans var. natans is currently threatened with extinction in some regions, including parts of Germany, where it has been protected since 1987. The plant produces hard, woody nuts with four sharp spines, which help anchor the plant to the waterbed and facilitate its propagation.

2. Trapa natans var. bispinosa

Trapa natans var. bispinosa, also known as the Asian water caltrop or Chinese two-horned water nut, is native to the tropical and subtropical regions of Asia. This variety is distinguished by its olive-green leaves, which often have reddish or reddish-brown veins. Unlike its European counterpart, Trapa natans var. bispinosa requires a tropical climate to thrive and produce fruits. The leaves of this variety are also arranged in rosettes and float on the water’s surface, but they tend to have a slightly different coloration. The fruits of Trapa natans var. bispinosa are notable for their two prominent spines, which help anchor the plant and facilitate its spread. This variety is commonly used in Asian cuisine and is cultivated for its edible seeds.
