Description

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.

Every Acorus gramineus 'Ogon' we send is a strong, well-rooted plant, hand-selected for healthy foliage and balanced shape, and packed with care to arrive in superb condition.

What to Expect

Seasonal by nature: what to expect

  • Grown outdoors, the way nature intended. Weather-tested and hardened in real UK conditions, so they thrive in your garden. A few marks on the older leaves are normal, the sign of a tough, real plant rather than a flaw.
  • It follows the seasons. Depending on when you order, your plant may arrive cut back, dormant or leafless. That's healthy: dormancy is the ideal time to plant.
  • Posted, not posed. Big leafy plants like bananas and gingers may be trimmed or gently folded to travel safely. It does the plant no harm, and it powers away again in spring.

Not sure what to expect from yours? Dormant, cut-back or weather-marked plants are all perfectly healthy and normal. Read what to expect through the seasons

Frequently Asked Questions

How do you care for Acorus '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.

How big does Acorus 'Ogon' get?

'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.

Can you grow Acorus 'Ogon' in pots?

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.

Does the yellow hold through winter?

Yes, in most UK winters. 'Ogon' is semi-evergreen, so the gold-and-green striped foliage often persists right through to spring, providing welcome winter interest. In harsh winters the foliage may die back to the rhizome, but it regrows in spring.

Is Acorus 'Ogon' fully hardy?

Yes. 'Ogon' is rated RHS H7, fully hardy to around -20C. It thrives across the UK with no winter protection needed.

What pairs well?

A natural partner for hostas, ferns and tree ferns in an exotic border. The golden tone illuminates a sea of green and complements the cool blues of hosta foliage especially well.

Does my plant come with a pot?
Your plant will arrive in its nursery grow pot — the plastic pot it's been growing in. We don't include a decorative pot as standard, and there's a good reason for that: it means you get to choose one that fits your space and style, rather than being stuck with something that doesn't suit your home.

It also means you're not paying extra for a pot you might not want. The nursery pot is perfectly fine to keep your plant in for a while, just pop it inside a decorative cover pot or cache pot and you're good to go. When you're ready to repot (usually after a growing season or when roots start poking out the bottom), you can move it into something more permanent with fresh soil.

If you're not sure what size cover pot to go for, check the pot selector tool listed above, you'll want a decorative pot that's a centimetre or two wider than that to give it a comfortable fit.
How big will my plant be when it arrives?
Every plant on our site includes the pot size (e.g. 12cm) and, where possible, an approximate height. That's the most reliable way to set your expectations, photos can sometimes make a plant look larger or smaller than it really is.

If you're thinking "that sounds quite small for the price," here's something worth knowing: younger, smaller plants almost always adapt better to your home than larger ones. They adjust faster to your light and humidity, put out new growth more quickly, and tend to establish stronger root systems long-term. A plant that grows into your space will usually outperform one that was already big when it arrived.

That said, every plant is an individual. The one you receive may vary slightly in height, shape, or fullness compared to the photo, that's the nature of living things, not a quality issue. We select healthy, well-established specimens, and if you ever feel your plant doesn't match what you were expecting, just get in touch and we'll take a look.
What makes your plants different from the supermarket or garden centre?
There's a big difference between a plant that's been sitting under on a retail shelf and one that's been looked after and cared for by people who specialise in exactly this.

Our plants are grown in house or sourced from specialist nurseries, many of them varieties you simply won't find at your local garden centre or supermarket. Before anything leaves us, it's checked over by our horticultural team to make sure it's healthy, well-rooted, and ready to thrive in your home. We're not shifting volume off a pallet, we're choosing plants we'd want to keep ourselves.

When you buy from a supermarket, you get a plant and a generic care label. When you buy from us, you get the knowledge that comes with it, detailed care guidance, a team you can actually contact if something isn't going right, and the confidence that what's arriving has been looked after properly from the moment it was grown to the moment it reaches your door.

We're a specialist nursery first, not a retailer that happens to sell plants. That's the difference, and you'll see it the moment you open the box.
What should I do when my plant arrives?
First things first, unbox it as soon as you can. Plants don't love being in dark boxes any more than you would, and the sooner yours is out and breathing, the better.

Remove all the packaging carefully, give the soil a check with your finger, and water lightly if it feels dry. Then find it a spot with appropriate light, but avoid putting it straight into harsh direct sun or next to a radiator. Think of it like arriving somewhere new after a long journey: it needs a moment to adjust.

It's completely normal for your plant to look a little tired or droopy after transit. This is called transit stress, and most plants bounce back within a week or two. You might see a yellow leaf or some drooping, don't panic, and resist the urge to overwater or start repotting straight away.

Our advice for the first couple of weeks: leave it in its nursery pot, water it only when the top layer of soil feels dry, and let it acclimatise to your home's light, temperature, and humidity. Once it's settled in and showing signs of new growth, you can think about repotting or moving it to its permanent spot.

Every plant we sell comes with a care guide on the product page so you'll know exactly what it needs going forward. And if anything doesn't look right, get in touch with our team, we're always happy to help.
Will my plant survive being shipped?
Yes! and we go to serious lengths to make sure of it. Every plant is hand-packed by our team with protective wrapping and secure, custom-designed boxes to keep it stable and safe in transit. We've shipped hundreds of thousands of plants across the UK and our packaging methods have been refined over years to handle the bumps and jolts of delivery.

During colder months, we monitor weather forecasts and offer heat packs where needed to protect against frost. In extreme conditions, we may hold your order for a day or two rather than risk sending it out, we'd rather you wait an extra day than receive a stressed plant.

That said, plants are living things, and the occasional transit wobble can happen. If your plant arrives damaged or isn't in the condition you'd expect, just get in touch within 48 hours with a photo, and we'll make it right, whether that's a replacement or a full refund. No fuss.

The short version: we treat every box like it's going to someone who really cares about what's inside, because it is.
