ʻAhuʻawa

Mariscus javanicus
A greenish blue rush with linear leaves 40-110 cm. long. The flower clusters emerge umbrella like at the surface with many tiny spikelets (which contain the seed.) The margins of the leaves are very coarse and abrasive.

This is an indigenous plant native to tropical Africa, Asia as well as Hawaiʻi. Here it is found on all of the major islands except Kahoʻolawe but also found on Midway atoll. Ahuawa is common in marshes, loi (kalo patches), along side streams and ditches, coastal pastures, rocky coastal sites, and cliffs.

Ahuawa thrives in moist soil and full sun, therefore it is an excellent plant for the outside pond. The color of the leaves also adds great contrast to accentuate rock features.

ʻŌlelo Hawaiʻis use the pounded stems of this plant to strain pulp out of awa- a drink made from the pound root of the awa plant Piper methysticum.
