Description

Hosta fortunei 'Ki Ren Jyaku' is a striking Japanese plantain lily grown for its glowing yellow foliage and, unusually, its beautiful double flowers. The broad, softly textured leaves hold a rich buttery yellow through the season, and in summer it produces pale lavender double blooms that mark it out as a real collector's hosta.

A fully hardy, deciduous herbaceous perennial (RHS H7), it dies back to the ground in late autumn and returns in mid to late spring, so expect bare soil over winter. The nectar-rich flowers are enjoyed by bees. For more on the seasonal habit of hardy exotics, see our what to expect guide.

The luminous yellow leaves light up an exotic border or a shady corner and grow just as well in a large container. With its double summer flowers it also sits happily among shade-loving plants for pollinators. Set it against darker-leaved varieties such as Hosta 'First Blush' for contrast.

Every plant is nursery-grown, part of our wider hardy exotics range, and carefully packed 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 Hosta 'Ki Ren Jyaku' hardy in the UK?

Yes. Ki Ren Jyaku is fully hardy across the UK, rated RHS H7. As a deciduous perennial it dies back in late autumn and returns each spring, needing no winter protection.

Does Hosta 'Ki Ren Jyaku' need sun?

It grows in partial shade, but a little gentle morning or afternoon sun brings out the strongest yellow leaf colour; too much deep shade turns it greener. It is still a fine choice among plants for shade.

Does Hosta 'Ki Ren Jyaku' really have double flowers?

Yes. This unusual Japanese variety produces pale lavender double flowers in summer, which is rare among hostas and part of what makes it a collector's plant.

Are hostas poisonous to dogs and cats?

Yes. Hostas contain saponins that are toxic to cats, dogs and horses if eaten, and can cause vomiting, diarrhoea and loss of appetite. Plant them where curious pets are unlikely to nibble the leaves.

Can I grow Hosta 'Ki Ren Jyaku' in a pot?

Yes. It grows well in a pot or the ground; in a container use loam-based compost, keep it moist and give it a little sun for the best colour. See more plants for pots.

Do hostas come back every year?

Yes. Hostas are deciduous perennials that die back to the crown in late autumn and re-emerge in mid to late spring. Our what to expect guide explains the seasonal cycle.

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.
