Maranta arundinacea, also known as arrowroot, maranta, West Indian arrowroot,obedience plant, Bermuda arrowroot, araru, araruta, ararao or hulankeeriya, is a large, perennial herb found in rainforest habitats of the Americas, but cultivated in tropical regions worldwide.
Description
The root of M. arundinacea.
Arrowroot is a perennial plant growing to a height of between 0.3 m (1 ft) and 1.5 m (5 ft). Its leaves are lanceolate. The edible part of the plant is the rhizome. Twin clusters of small white flowers bloom about 90 days after planting. The plant rarely produces seeds and reproduction is typically by planting part of a rhizome with a bud. Rhizomes are ready for harvesting 10–12 months after planting as the leaves of the plant begin to wilt and die. The rhizomes are fleshy, cylindrical, and grow from 20 cm (8 in) to 45 cm (18 in) long.[3]
The arrowroot plant probably originated in the Amazon rainforest of northwestern Brazil and neighboring countries. It grows best between temperatures of 23 °C (73 °F) and 29 °C (84 °F) with annual precipitation between 150 cm (59 in) and 200 cm (79 in). The dormant rhizomes can withstand temperatures as low as 5 °C (41 °F).[4]
In the continental United States, arrowroot is cultivated as an outside plant only in southern Florida.
