The rush grass, also known as water bamboo or windmill grass, is a perennial herb in the Cyperaceae family, belonging to the genus Cyperus. Its stems are straight and slender, with leaf-like bracts clustered around them in a radiating pattern, exuding a graceful and elegant demeanor, reminiscent of bamboo's charm. Hence, it is highly favored by people, often used for pot plants or as cut flowers. Originating from distant Africa, it has long been extensively cultivated in our country.

Based on the characteristic of the umbrella grass that can grow both in water and on land, using a rectangular, leak-proof planter, arrange several clumps of the flower with varying heights, leave some water surface exposed, and add a few decorative stones. This can create a natural water scene, with the scattered shadows and pleasant scenery, exuding a unique charm.

Common variants include: Dwarf Sedge (Cyperus alternifolius cv. nanus), Silver Line Sedge (Cyperus alternifolius cv. striatus), where "striatus" means "lined."
