Description 

Acorus gramineus ‘Argenteostriatus’ is a compact, beautifully variegated form of Japanese Sweet Flag, prized for its fine, grass‑like leaves striped with creamy white. This plant brings brightness, texture, and movement to pond edges, making it ideal for smaller ponds, container water gardens, and refined marginal schemes.

Unlike the taller Acorus calamus forms, this cultivar stays neat and low, forming elegant clumps that soften hard edges and provide subtle fragrance when the foliage is crushed. A superb choice for wildlife ponds, contemporary planting, and naturalistic designs.
