Description

The Acer shirasawanum 'Moonrise', a refined small full moon maple, is one of the most rewarding Japanese-style trees you can grow in a British garden. From the moment its leaves unfurl in spring, this slow-growing specimen puts on a three-act colour show that few other shrubs can match: bright red new foliage in spring, glowing yellow-green and chartreuse through summer, and a final flourish of orange and scarlet in autumn. It is a true focal-point plant, prized on the most discerning UK collectors' lists yet still rare enough at the garden centre to feel like a find.

What sets 'Moonrise' apart from a regular Japanese maple is its parent species. Acer shirasawanum is the Shirasawa maple, distinguished by larger, fuller, rounded palmate leaves that read as more substantial on the shrub than the lacy forms of Acer palmatum. This selection, originally a Buchholz Nursery introduction (registered as 'Munn 001'), is notably more resistant to leaf scorch than most full moon maples, making it one of the safest choices for a brighter spot.

'Moonrise' is compact enough to live happily in a generous container for years, making it a star choice for a patio specimen tier or a sheltered courtyard. In the ground, give it a quiet spot where its colour can be seen against an evergreen backdrop, and shelter it from cold drying winds and late spring frosts. Mulch each spring with leaf mould and water deeply through the first two summers to lock in establishment.

Whether you are searching for Acer shirasawanum 'Moonrise' UK stock or a special Japanese maple Moonrise as a focal point in your Hardy Exotic garden, this is the kind of specimen that earns its place even in a small plot. It plays beautifully against tree ferns and bamboos in an exotic border, and works equally well in a shaded woodland-style planting. See our what to expect from outdoor plants guide for seasonal notes.

Every Acer shirasawanum 'Moonrise' we send is a strong, well-rooted graft, hand-selected for a healthy crown 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 Acer 'Moonrise'?

Acer shirasawanum 'Moonrise' is a low-maintenance specimen once established. Plant in moist, free-draining soil on the acid to neutral side, in dappled or partial shade where it gets shelter from cold drying winds and hot afternoon sun. Water deeply through the first two summers and mulch each spring with leaf mould. See our Hardy Exotics seasonal guide for what to expect through the year.

How big does Acer shirasawanum 'Moonrise' get?

'Moonrise' is one of the more compact full moon maples. Expect a slow-growing, loosely rounded shrub of around 2-3 metres tall and 1.5-2.5 metres wide after ten to twenty years. It is well suited to smaller gardens and large containers where bigger Japanese maples would outgrow the space.

Can you grow Acer 'Moonrise' in pots?

Yes. 'Moonrise' is a good choice for patio pots and containers. Use a generous pot of at least 40 litres, fill with a peat-free, free-draining loam-based compost on the acid to neutral side, and stand the pot somewhere sheltered with dappled shade. Top-dress and feed each spring, water through summer to keep the rootball reliably moist, and repot every two to three years.

How is 'Moonrise' different from Acer 'Autumn Moon'?

Both are Acer shirasawanum selections from the same family of full moon maples. 'Autumn Moon' has more bronze-orange summer foliage and is a slightly looser, more upright shrub. 'Moonrise' is more compact, starts the season with vivid red new growth that fades to fresh yellow-green by midsummer, and is reported to be more resistant to leaf scorch in brighter spots.

Is Acer 'Moonrise' fully hardy in the UK?

Yes. Acer shirasawanum 'Moonrise' is rated RHS H6, meaning it is hardy down to around -20C once established. It thrives across most of the UK including colder northern gardens. The only winter risk is late spring frosts that can singe newly emerged foliage; planting in a sheltered spot or courtyard easily mitigates this.

When does Acer 'Moonrise' look its best?

'Moonrise' offers a three-act colour show across the year. Spring brings vivid red new foliage on the freshly emerged leaves. Summer settles to a fresh yellow-green and chartreuse as the leaves mature. Autumn is the showstopper, with the whole canopy turning bright orange and scarlet before leaf fall. It looks especially good paired with tree ferns and exotic foliage.

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.
