Monstera unniiae is a holy grail plant: a recently discovered Monstera mutation that has barely entered cultivation and is almost never offered in the UK. This listing is for a large, established plant in a 15cm pot,
Care
Treat it like any other Monstera: bright indirect light, a chunky mix from our aroid substrate range, water once the top few centimetres dry, and humidity of 60 percent or more. Give it a pole from our moss pole collection and the leaves will size up dramatically. Keep it above 15C year round.

We pack every order in protective, sustainable packaging designed to keep your plants safe in transit, and every plant is checked before it ships.

About Monstera unniiae
Monstera unniiae is a rewarding challenge of a houseplant. It needs bright indirect light, watering once the top 2 to 3cm of compost has dried out, high humidity and a minimum temperature of 15°C. It is harmful to pets and small children if eaten.
Bright indirect light suits it best. Shield it from harsh midday sun, which can bleach and scorch the foliage.Read moreShow less

Monstera unniae is one of the rarest Monstera species in cultivation, only recently described and still almost never offered for sale in the UK. This listing is for a large, established plant in a 15cm pot.
Is Monstera unniae difficult to grow?
We rate it advanced, mostly because of its rarity and value rather than fussiness. Give it steady warmth, good humidity, bright indirect light and a chunky aroid mix and it grows like a typical climbing Monstera.
Is it safe around pets?
No. Like all Monsteras it contains calcium oxalate crystals, which irritate the mouth and stomach if chewed. Keep it out of reach of pets and small children.
Does it need a moss pole?
Yes, in time. It is a climbing aroid, and leaves size up dramatically once it is growing vertically on a moss pole or similar support with its aerial roots in contact with something moist.
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.
