Description

Euphorbia x martini 'Walberton's Little Treasure', a compact form of Martin's spurge, is one of the brightest new evergreens for a sunny British garden. It forms a neat, dome shaped mound of narrow foliage in a glowing shade of yellow, lit by lime tinted new growth in spring and warm copper tips when the weather turns cold. Over a long spring to summer season it is topped with airy heads of zesty lime-green flowers, each with a tiny red eye, giving months of colour on a plant that rarely climbs above knee height.

Bred in the UK and released in 2025, this is a genuinely hardy exotic. Rated RHS H5, it shrugs off hard frost once established and keeps its golden foliage right through winter, so there is no bare season to wait out. It is also impressively drought tolerant, thriving on poor, gritty soils and in hot, dry corners where thirstier plants struggle. Explore the rest of our hardy exotics to build a scheme that looks good all year.

Its low, mounded habit makes it a natural for pots and containers, for the front of exotic borders, and for dry and gravel gardens where its sculptural, evergreen form earns a place among our architectural foliage. Water regularly through the first summer to establish a strong root system, after which it needs very little beyond a light trim of faded flower stems. Wear gloves for that job, as the milky sap is a skin and eye irritant and is harmful if eaten.

For a picture of how hardy exotics settle in and change through the seasons, see our guide on what to expect. Every plant we send is nursery-grown, hand-selected for a healthy crown and strong roots, and packed with care to arrive in top 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

Is Euphorbia 'Walberton's Little Treasure' hardy?

Yes. It is rated RHS H5, so it is fully hardy across most of the UK and takes hard frost once established. Being evergreen, it holds its golden foliage right through winter. In very cold, wet gardens the main risk is winter wet at the roots, so give it sharp drainage and a sheltered spot.

How big does Euphorbia 'Walberton's Little Treasure' grow?

It is a genuinely compact spurge, reaching only about 30 to 40 cm tall and wide. It forms a neat, dome shaped mound that stays tidy at the front of a border, in a gravel garden, or in a pot, without the sprawl of larger euphorbias.

Where is the best place to plant it?

Give it full sun for the brightest yellow foliage, though it also copes with light or partial shade. It loves free-draining soil and is ideal for hot, dry spots. It is a natural choice for dry and gravel gardens and for the front of exotic borders.

Is Euphorbia 'Walberton's Little Treasure' evergreen?

Yes, it is evergreen and earns its keep all year. The foliage is a bright, glowing yellow, with lime tinted new growth in spring and warm copper tips when temperatures drop in autumn and winter, so there is colour even in the coldest months.

Is it poisonous to pets or children?

Take care when handling it. Like all euphorbias, the milky white sap is a skin and eye irritant and is harmful if eaten, so wear gloves when cutting it back and keep it away from children and pets. Wash off any sap that touches skin promptly.

Can I grow Euphorbia 'Walberton's Little Treasure' in a pot?

Absolutely. Its compact, drought tolerant habit makes it one of the best euphorbias for containers. Use a peat-free compost with added grit for drainage, water while it establishes, then only in dry spells. See more of our plants for pots and containers.

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.
