Fountain Grass

A soft, textural grass that brings movement and lightness to the garden

Fountain Grass adds gentle structure and year‑round interest with its arching form and feathery plumes. It’s a versatile, low‑maintenance ornamental grass that works beautifully in layered planting, borders, and modern landscapes. In SEQ’s warm climate, it thrives with very little care and provides reliable texture throughout the seasons.
