Phalaris arundinacea REED CANARY GRASS (plant)

Reed canary grass, also known as gardener's garters, ribbon grass, or Phalaris arundinacea in Latin, is a perennial grass of Eurasian origin. It is a fast-growing, monocotyledonous species belonging to the Poaceae family. It typically reaches 50 cm in height and forms a dense clump.

The evergreen foliage of Phalaris is characterized by long, narrow, and often flat leaves. The highly decorative leaves are green and white, appearing striped and feeling slightly rough to the touch.

Root system of ribbon grass is rhizomatous, allowing it to spread and form dense colonies. This type of root contributes to its drought resistance and enables the plant to establish itself in various soil types.

Gardener's garters seeds are small, thin, generally oval, and brownish to blackish in color. They are contained in a panicle-shaped inflorescence that transforms into a spike during maturation. The seeds are easily dispersed by the wind.
