Cabomba is an herbaceous, submerged, rooted aquatic perennial. It can also survive in a free-floating state for six to eight weeks. Cabomba often grows in water from 0.4 – 1.2 m and up to 6 m deep. The plant has both submersed and floating leaves. Submersed leaves are oppositely arranged and 1 – 3.5 x 1.5 – 5.5 cm on petioles up to 4 cm long and finely dissected. Floating leaves are blades 0.6 – 3 cm x 1 – 4 mm with margins either notched or entire at base. Flowers are white to purplish or yellow.
