Water hyacinth (Eichhornia crassipes) is a fast-growing aquatic plant native to the Amazon basin, but now commonly found in tropical and subtropical regions around the world—including Vietnam, especially in the Mekong Delta.

Known in Vietnamese as “lục bình”, this plant floats gracefully on rivers and canals with its thick green leaves, delicate purple flowers, and bulbous stems. Although once considered an invasive species due to its rapid spread, water hyacinth has become an incredibly valuable natural material for eco-friendly handicrafts.

When harvested, dried, and processed, the stems become a durable, flexible fiber—ideal for weaving baskets, trays, mats, bags, and even furniture. Its rustic texture and earthy tone give each handcrafted item a warm, natural charm.

Seagrass, locally known as "cói lác", is a natural wetland plant commonly found in the coastal and riverine areas of Vietnam. Its scientific name is Cyperus malaccensis Lam, and it grows abundantly in provinces such as Thanh Hóa, Ninh Bình, Trà Vinh, Sóc Trăng, and Vĩnh Long.

Seagrass is a grass-like plant with long, slender, slightly rough stems that turn from green to pale golden-brown when dried. It typically reaches 60–100 cm in height and features small, round flower clusters at the stem tips. Its fibrous roots help it anchor firmly in muddy or sandy soils, playing a role in preventing erosion along riverbanks and coastal zones.

After harvesting and sun-drying, seagrass becomes a strong, flexible, and eco-friendly material widely used in weaving mats, baskets, rugs, trays, and home décor products. Its rustic texture and natural color give each handmade item a warm, earthy appeal.
