Sparganium consists of deciduous or semi-evergreen, marginal aquatic perennials that form dense clusters of robust foliage. The leaves are slender and upright, while the flowers are small, giving way to fleshy, burr-like fruits.

Sparganium erectum is a robust, upright, semi-evergreen perennial that thrives in marginal aquatic settings. Its leaves are long and linear, reaching lengths of up to 1.5 meters, featuring a distinctive keeled shape. During the summer months, this plant develops branched stems that bear clusters of greenish-white male and female flowers, which are arranged separately. After flowering, it produces spiny fruit that starts as green and matures to a brown color, measuring up to 1 centimeter in diameter.
