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

The Hydrangea Midnight Pearl (Hydrangea macrophylla 'Midnight Pearl') is a striking mophead from the Midnight series, prized for its near-black stems and dark foliage that frame cool white flower heads through summer. This black-stem hydrangea brings real drama to a planting scheme, and as the pearly blooms age they soften to a gentle pink for a long season of interest.

Fully hardy across the UK, it is a dependable deciduous shrub that settles happily into borders and large pots alike. As a white mophead hydrangea it will not turn blue like the coloured forms, so you get clean, reliable colour whatever your soil. Leave the faded heads in place over winter, where they catch the frost beautifully and shelter next year's buds.

How and where to grow

  • Position: sun to part shade, with shelter from hot midday sun. It is a lovely choice for a shady spot and dappled corners.
  • Soil: moist but well-drained, fertile soil that does not dry out.
  • Size: a rounded shrub reaching around 1 to 1.5 m tall and wide.
  • Hardiness: fully hardy (RHS H5) and deciduous.

Water freely through the first few summers to build a strong root system, especially in containers where it dislikes drying out. In spring, cut back to a strong pair of buds to keep it shapely. It is superb at the front or middle of exotic borders, and just as happy in a large pot among your other plants for pots.

Part of our hardy exotics range, every Hydrangea Midnight Pearl is nursery-grown and carefully selected for a healthy shape and strong roots. For a guide to seasonal changes and what to expect on arrival, see our what to expect page.

Hardiness & Frost

Fully hardy across the UK (RHS H5). Deciduous; leave old flower heads on over winter to protect the buds.

  • No, the white flowers age to soft pink; only the coloured mopheads turn blue on acid soil.

  • In sun to part shade with shelter from hot midday sun and moist but well-drained soil. It is a great pick for plants for shade.

  • Leave old heads over winter, then cut back to a strong pair of buds in spring.

  • Yes, in a large pot of loam-based compost; keep it well watered. It sits happily among your other plants for pots.

  • For its near-black stems and dark foliage that set off the pearly white flowers.

  • A rounded shrub to around 1 to 1.5m tall and wide.

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

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. Whether grown in our own nursery or sourced from trusted partner growers, every plant is checked before it ships. On the rare occasion something isn't right on arrival, we'll make it good, provided the plant is still in its original nursery pot.

When to prune · Early spring, once hard frosts pass

Mophead that flowers on last year's wood — leave the old flowerheads on over winter, then in early-to-mid spring cut them back to the first fat pair of buds and remove one or two of the oldest stems at the base to renew the plant.
