Elegant evergreen perennial grass with golden-green foliage that brightens ponds, borders, and shaded gardens all year round.

Acorus gramineus ‘Ogon’ (Golden Variegated Sweet Flag) is a moisture-loving, semi-aquatic perennial prized for its soft, arching leaves striped in yellow and green. Its graceful, grass-like form adds movement, texture, and light to areas where few plants thrive — especially damp or shaded spots near ponds, water features, and boggy beds.

Compact, hardy, and easy to grow, this versatile perennial keeps its golden tones throughout the year, creating calm, natural contrast in both traditional and modern garden designs. Perfect for pairing with ferns, hostas, or irises, Acorus ‘Ogon’ enhances any planting scheme with elegance and reliability.

Supplied in a 17cm / 2L garden-ready pot, this well-established plant offers instant impact and long-term performance. Low-maintenance and fully hardy in UK conditions, it’s an ideal choice for gardeners seeking dependable colour, structure, and texture across all four seasons.
