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

FloweringMay-Jun

Frangula alnus 'Fine Line' (also sold as Rhamnus frangula 'Fine Line', the Fine Line Buckthorn) is a narrow, upright deciduous shrub grown for its fine, ferny foliage and tidy columnar shape. It brings the soft texture of a conifer with the lightness of a deciduous plant.

The slender, glossy green leaves are almost willow-like and turn a clear buttery gold in autumn before falling. Small greenish flowers in May and June are quietly attractive to pollinating insects. Its tall, slim outline, roughly 2m high but under a metre wide, makes it one of the most useful plants for tight spaces.

How and where to grow

  • Position: Full sun to partial shade. The densest, best foliage forms in an open, sunny spot.
  • Soil: Adaptable to any moist but well-drained soil on chalk, clay, loam or sand, and it tolerates damp ground.
  • Size: Around 1.5 to 2m tall and just 0.6 to 0.9m wide.
  • Hardiness: Very hardy (RHS H6), fully hardy with no winter protection.

That narrow habit makes 'Fine Line' ideal for a slim screen or informal hedge where a wider shrub would not fit, and its strong vertical form is a real asset for architectural planting. Group several for a living column effect in exotic borders or a modern courtyard.

It sits happily among other hardy exotics. Every plant is nursery grown and hand picked. To see how our outdoor plants arrive and settle in, read what to expect from hardy exotics.

Hardiness & Frost

Very hardy across the UK, rated RHS H6, tolerating well below -15C. No winter protection needed.

Sun & Aspect

Full sun to partial shade. The densest, best foliage forms in an open, sunny position.

Soil

Adaptable to any moist but well-drained chalk, clay, loam or sand, on any pH. Tolerates damp ground.

Watering & Establishment

Water through the first year, especially in dry spells. Once established it is tough and low maintenance.

  • It stays very narrow, roughly 1.5 to 2m tall but only 0.6 to 0.9m wide, which is what makes it so useful in tight spaces.

  • Yes. Its slim, columnar habit makes it ideal for a narrow screen or informal hedge where a wider shrub would not fit. Plant several in a row for a living column effect.

  • It does. The fine, ferny green leaves turn a clear buttery gold in autumn before falling, adding a soft vertical accent to architectural planting.

  • Yes. Frangula alnus 'Fine Line' is the same plant as Rhamnus frangula 'Fine Line', the Fine Line Buckthorn. Frangula alnus is the current accepted botanical name.

  • Almost none. It holds its narrow shape naturally. Trim lightly in late winter only if you want to tidy it or restrict its height, then let it sit among your other hardy exotics.

  • Yes. The raw berries and the bark are strongly purgative and toxic if eaten, so keep pets and children from nibbling any part of the plant. 'Fine Line' sets very little fruit in any case.

  • 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.
