Tambo is a coarse, erect grass growing to a height of 1.5 to 3.5 meters. Stems are cylindrical and hollow, about 1 centimeter in diameter. Leaves are flat and linear, up to 50 centimeters long, 2.5 centimeters wide. Panicles are large, terminal, plume-like, somewhat nodding, 30 to 50 centimeters long, brownish, dense, very many-flowered, with slender branches. Spikelets are linear, and about 1 centimeter long.

Edibility / Nutrition
-Edible parts: Leaves, roots, seed, stem.
– Young shoots may be eaten raw or cooked and eaten like labong (bamboo sprouts).
– Unfolded leaves used as potherb.
– In Japan, young shoots are eaten, cooked like asparagus or bamboo sprouts. Also, grounded dry young leaves, mixed with cereal flour in making dumplings.
– Sugary gum from the stem can be rolled into balls and eaten as sweets.
– Powder extracted from dried stems can be moistened and roasted like marshmallow.
– Stems can boiled
– The roots and sprouts are cooling and diuretic.

– Mouth pieces for musical instruments (clarinets, etc.)
• Pharmacologic Study: Study of aerial parts of P. communis Trin. was done concerning free amino acids, fatty acids, sterols, tocopherols and polyphenols. Isolated polyphenols were investigated for antibacteriophage properties.
• Phytotoxin / Gallic Acid: – Study on plant invasiveness behavior showed P. australis (common reed) secretes a phytotoxin, gallic acid, which on ultraviolet light photo-degradation, causes higher mortality of susceptible seedlings, that gives it a competitive edge in their habitats.
• Phytoremediation / Gallic Acid: Phytoremediation of selected pharmaceuticals (diclofenac, ibuprofen, and acetaminophen) using Armoracia rusticana and Linum usitatissimum cell cultures and by hydroponically cultivated Lupinus albus, Hordeum vulgaris, and Phragmites australis plants in laboratory conditions was done. Best effectiveness for ibuprofen removal was found with Phragmites.
