Winter 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.
Senecio maritima 'Silver Dust', better known as Dusty Miller and correctly named Jacobaea maritima, is grown for its finely cut, silver-white felted foliage that lights up borders, pots and gravel gardens. The deeply lobed leaves are covered in soft, felty hairs that give the whole plant a cool, almost metallic shimmer. It is a brilliant foil for stronger colours and a favourite for adding contrast to sunny planting.
This is first and foremost a sun-loving foliage plant. In its second year it may throw up small, mustard yellow daisy flowers, though many gardeners trim these off to keep the focus on the silver leaves. It is borderline hardy, so it is often grown as seasonal bedding or given a little winter protection in colder gardens. For what to expect from tender and borderline hardy plants outdoors, see our hardy exotics what to expect guide.
Water to establish, then keep it on the dry side, as it is genuinely drought tolerant once settled. Its love of sun and free-draining ground makes it a natural for coastal and exposed gardens and for drought tolerant planting. The tidy habit and silver colour also make it one of the best foliage plants for pots and containers, where it sets off bright summer flowers beautifully.

Live Arrival Guarantee
All plants are covered by our 7-day live arrival guarantee. We pack every order in protective, sustainable packaging designed to keep your plants safe in transit, and every plant is checked before it ships. On the rare occasion something is not right on arrival, we will make it good, provided the plant is still in its original nursery pot.
Ordering in autumn or winter? Many hardy exotics arrive dormant or cut back right now. This is normal, and the best time to plant.
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.

About Dusty Miller
Senecio maritima 'Silver Dust' (Dusty Miller) needs full sun and well-drained soil. It is half-hardy to around −5°C and needs protection from hard frost.
light, sharply drained soil. Chalk, loam and sand all suit it, and sharp drainage matters more than richness.
Watering
Water to settle it in, then keep on the dry side. Once established it is genuinely drought tolerant and needs watering only in long dry spells. Overwatering, not neglect, is the usual cause of failure.Read moreShow less

Toxicity
Can be harmful if eaten. The foliage contains compounds that may cause stomach upset, so keep it away from curious pets and children.
Is Senecio 'Silver Dust' hardy, and will it survive winter?
It is borderline hardy (RHS H3), coping with a few degrees of frost but not a hard or wet winter. In mild, free-draining gardens it often comes through, especially in coastal and exposed spots. In colder or heavier gardens, treat it as seasonal bedding or give it winter protection under cover.
Where is the best place to plant Dusty Miller?
Give it full sun and sharp drainage. The brighter the spot, the whiter and denser the foliage. It thrives on light chalky, loamy or sandy soils and is happy in drought tolerant and gravel plantings. Avoid damp, shaded corners, where it tends to rot.
Does Silver Dust flower?
Yes, usually in its second year it produces small mustard yellow daisy flowers in summer, roughly June to August. Many gardeners snip these off to keep the plant compact and focused on its silver leaves, though the flowers are useful to pollinators if you leave them.
How much watering does Silver Dust need?
Very little once established. Water to settle it in, then keep it on the dry side. It is genuinely drought tolerant and only needs watering in long dry spells. Overwatering, rather than neglect, is the most common cause of failure, so err on the side of dry.
Can I grow Silver Dust in pots and containers?
It is one of the best silver foliage plants for pots and containers. Use a free-draining, gritty compost, keep it in full sun, and let it set off brighter summer flowers. Containers also make it easy to move plants under cover for winter.
Is Dusty Miller poisonous to pets?
It is best treated as harmful if eaten. The foliage contains natural compounds that can cause stomach upset, so keep it away from curious pets and children. If you think a pet has eaten a quantity, contact your vet for advice.
Are your plants treated with pesticides?
We aim to avoid using pesticides where possible, but we can't control the whole supply chain.
If the plant is going into a vivarium, terrarium or aquarium with live animals, rinse the leaves and roots well, remove any soil and let the plant dry out before adding it. We'd also suggest keeping it away from animals for a month first.
Can I see a photo of the exact plant I'll receive?
We're not able to send photos of individual plants or let you choose a specific one, as plants are selected by our team when your order is packed. Our photos show the variety and the kind of plant you can expect, and yours may vary a little in height, shape or fullness.
If a size has a code next to it, such as 9cm / B2, you're buying the exact plant pictured.
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 7 days 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.
Every order is hand-packed in eco-friendly, protective packaging - refined through thousands of deliveries to ensure your plant arrives healthy, hydrated, and looking its best.
