Arrowroot, or obeience plant (Maranta arundinacea), is a large perennial herb of genus Maranta found in rainforest habitats. Arrowroot is also the name for the easy-to-digest starch from the rhizomes (rootstock) of West Indian arrowroot. This plant should be confused neither with Sagittaria species sometimes called "arrowhead" and used as a root vegetable nor arrowweed, which also has edible roots.
