The common arrowroot is Maranta arundinacea, known as dong, dong củ, dong ta or bình tinh in Vietnamese. They are widely-cultivated in southern Vietnam for its roots. Arrowroots are often eaten as a snack by simply boiling them in water. Its powder form is used in making several local cakes such as bánh thuẫn cupcake or bánh in. The powder is considered as more fragrant than common tapioca starch or glutinous rice powder.

Stachyphrynium placentarium is known as “dong lá” in Vietnamese and this plant is considered as a wild arrowroot plant which is cultivated in northern Vietnam only for its leaves.(lá dong).

False arrowroot (Curcuma pierreana, Vietnamese: bình tinh chét) is smaller than arrowroot, and its usage is similar. This plant grows in several central Vietnam provinces. However, the plant is unknown throughout Vietnam so its cultivation area is reduced, and probably forgotten.
