Description

Sarcococca saligna, the Willow-leaf Sweet Box, is the most distinctive of the sweet boxes, with long, narrow, willow-like evergreen leaves that give it a soft, arching elegance the others lack. In late winter it carries slender greenish-white flowers, a little more subtle in scent than its cousins, followed by handsome red-purple berries.

Fully hardy and thoroughly easy-going, it is one of the best evergreen shrubs for shade in a British garden. Like all our hardy exotics, it earns its place all year: glossy foliage in every season, winter flower and autumn fruit. See our what to expect guide for how it changes through the seasons.

Its bushy habit suits a shady border, a low informal evergreen screen or a shaded container by a path where you can enjoy the winter show. The flowers are valuable to early pollinators. For a richer, more powerful winter scent, pair it with Sarcococca ruscifolia.

Grown to nursery standard and sent out as strong, well-rooted plants ready to settle straight into the garden.

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

Where is the best place to plant Sweet Box?

Sarcococca is one of the finest shrubs for shade. It thrives in partial or full shade, including tricky north and east-facing spots, under trees and against shaded walls where little else will flower. Give it moist but well-drained soil and it settles happily. See more plants for shade and the wider hardy exotics range.

When does Sarcococca flower, and is the scent really that strong?

Yes. From December to March the small white or cream flowers release a powerful sweet fragrance that carries several metres on a still winter day, which is how it earned the name Sweet Box. The flowers are a lifeline for early bees and other winter pollinators, followed by black or red berries.

Is Sweet Box evergreen and how big does it get?

It is fully evergreen, holding glossy dark green leaves all year round. Size depends on the type, from low ground-covering forms around 0.5m to bushier kinds reaching 1 to 2m in height and spread over time. It is slow and steady, so it stays neat for years.

Can I grow Sarcococca in a pot?

Absolutely. Its compact roots and evergreen, fragrant habit make it ideal for a shaded doorway or courtyard container where you will catch the winter scent. Use a loam-based compost, keep it watered in summer and top-dress each spring. Browse more plants for pots and containers.

Does Sweet Box work as a low hedge or screen?

The taller, bushier forms make an excellent low evergreen hedge or informal screen in shade, clipped lightly after flowering to keep them dense. The dwarf ground-covering types are better used as under-planting. See other screening and privacy plants.

How much pruning and maintenance does Sarcococca need?

Very little. Sarcococca needs no routine pruning; simply trim lightly after flowering in spring to shape it or restrict its size. Mulch each spring, water through its first year, and it is otherwise one of the most trouble-free evergreen shrubs you can grow. Part of our hardy exotics collection.

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.
