Description

Hosta 'Catherine' is a beautiful blue-leaved plantain lily, its pointed, blue-green leaves marked by a bright chartreuse streak flaring up the centre that becomes creamier with age. The leaves are thick and waxy, which not only gives them their lovely blue bloom but also makes this one of the more slug-resistant hostas, an easy and rewarding choice for a shady spot.

Fully hardy right across the UK (RHS H7), it is a deciduous perennial that dies back each autumn and reshoots reliably every spring. Upright spikes of bell-shaped, pale lavender flowers appear in late summer. As it disappears over winter, pair it with evergreens for structure and see our hardy exotics: what to expect guide for seasonal timings.

The cool blue foliage is a wonderful foil in an exotic border and it grows just as happily in a container from our plants for pots range. The late-summer flowers draw in pollinators. For a contrasting gold-edged hosta, try Hosta 'Twilight'.

Part of our hardy exotics collection, every plant is nursery-grown, carefully selected for a strong crown and healthy roots, 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

Where is the best place to plant Hosta 'Catherine'?

Hosta 'Catherine' is happiest in partial to full shade, in a north or east-facing spot sheltered from hot afternoon sun. Deeper shade keeps the blue colouring at its best. Give it fertile, humus-rich soil that stays moist but never waterlogged. It is one of our best plants for shade.

Is Hosta 'Catherine' fully hardy in the UK?

Yes. It is rated RHS H7, fully hardy across the UK and tolerant of temperatures below -20C. Being deciduous it dies back in autumn and reshoots reliably every spring, so no winter protection is needed.

How big does Hosta 'Catherine' get?

It is a medium hosta, forming a mound around 30-40cm tall and 50-60cm across once fully established, reached over roughly two to five years. That makes it ideal for the front or middle of a shady border, or a pot.

Why are the leaves blue, and is it slug resistant?

The blue is a natural waxy coating on the thick leaves. That same waxy substance gives 'Catherine' good resistance to slugs and snails compared with thin-leaved hostas. Keeping it in shade preserves the blue, as strong sun melts the wax and the leaves look greener.

Can I grow Hosta 'Catherine' in a pot?

Yes. It grows very happily in a container of loam-based compost. Keep it well watered, feed through spring and summer, and never let the pot dry out. Browse more of our plants for pots.

Are hostas poisonous to cats and dogs?

Hostas are toxic to cats, dogs and horses if eaten, as they contain saponins that can cause vomiting, diarrhoea and lethargy. Site the plant away from pets that like to graze, and contact your vet if you suspect your pet has eaten any.

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.
