13cm / 1LWinter care: we are into the colder months. Protect newly planted or tender specimens from hard frosts, and hold off planting out until the frost risk has passed.
The Acorus gramineus 'Ogon', also known as the golden Japanese rush, is one of the most rewarding low-maintenance perennials for damp shade or pond margins. Its grass-like, gently arching foliage is striped lengthways in vivid gold and olive green, creating a low fountain of glowing yellow that lights up darker corners of the garden right through the seasons.
Despite looking like an ornamental grass, Acorus is actually in its own family, the Acoraceae. The leaves are semi-evergreen in mild winters and hold their colour beautifully into the cold months. It is fully hardy, untroubled by frost or wet feet, and ideal for the kind of damp, shaded sites that defeat most variegated plants.
Plant in groups of three or more for a sweep of golden colour. It is brilliant as an edge plant in a part-shaded planting or under taller exotic foliage in a Hardy Exotic border. It also works well in a damp patio container at the foot of a Japanese maple or palm. See our what to expect from outdoor plants guide for season-by-season notes.
A natural partner for hostas, ferns and tree ferns in an exotic border, where the golden tone illuminates a sea of green.

Outdoor plants are sold by the size of their pot — measured in litres, with the pot diameter in cm. A larger pot means a more established plant for quicker impact in the garden; a smaller pot is better value and soon catches up once planted out.
A young, vigorous plant and the most economical way to build up a planting. Give it a season or two and it will romp away.
A well-rooted young plant, ready to grow on in a border or container. Great value for filling space over a season or two.
A bushier, more established plant with a developed root system — a dependable middle ground that suits most gardens.
A strong, garden-ready plant that establishes quickly and makes a visible difference in its very first season.
A larger, fuller specimen for immediate presence — ideal when you want the planted look straight away.
A mature, substantial specimen — the quickest route to an established, fully planted-up feel.

Acorus gramineus 'Ogon'
Plant in consistently moist soil at a pond edge, in a bog garden or in a moisture-retentive border. Full sun to partial shade. Keep moist through the first season and tidy any tatty old leaves in spring. See our Hardy Exotics seasonal guide.
'Ogon' is a low-growing dwarf form. Expect a tight clump of around 25-30 cm tall and 25-30 cm wide. It is one of the most useful low-edge plants for damp shade.
Yes. It thrives in a damp patio container with loam-based compost. Keep the compost consistently moist; this is not a drought-tolerant plant. Pair at the foot of a Japanese maple or palm for a low golden mat that lifts the planting.
