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

Passiflora caerulea 'Constance Eliott' is the white-flowered form of the blue passion flower, and the cleanest white of any passion flower that can be relied on outdoors in the UK. Each bloom is a pure ivory-white star with a ring of white filaments and a contrasting purple centre, and they are lightly scented. Where the plain species gives you blue and white banded flowers, 'Constance Eliott' gives you a softer, cooler look that reads beautifully against dark foliage or a painted wall. It holds the RHS Award of Garden Merit.

Hardiness and seasons. Rated H4 by the RHS, so it copes with roughly -10C once established. The deeply lobed leaves are evergreen in mild gardens and semi-evergreen elsewhere; a hard winter may cut it back to the base, from where it reshoots in late spring. Flowers appear from midsummer into autumn, followed by egg-shaped orange fruits in a warm year. These are edible but bland, and the rest of the plant should not be eaten.

How and where to grow. Give it full sun or light shade against a warm, sheltered wall or fence, ideally south or west facing, with wires or trellis for the tendrils to grip. Any reasonably drained soil will do, from chalk and sand to loam, acid or alkaline. Good drainage matters more than fertility. It is vigorous: expect 8 to 12m of growth over 5 to 10 years if unchecked, though it is easily kept to a fence panel with an early spring prune.

Using it in the garden. Use it to clothe a pergola, an ugly fence or the sunny side of the house, or grow it in a large pot with an obelisk on a warm patio. It pairs well with blue agapanthus and silver foliage, and the flowers are visited by bees and hoverflies. It is a good choice if you want the exotic look of a passion flower without the blue, or as a partner to the plain species for a two-tone display.

Hardiness & Frost

H4, hardy to around -10C once established. May be cut to the ground in a hard winter and regrow from the base. Mulch the root zone in autumn and protect young plants in their first winter.

Sun & Aspect

Full sun or light shade on a sheltered south or west facing wall or fence.

Soil

Any well-drained soil, including chalk, sand and loam; acid, neutral or alkaline. Avoid waterlogged ground.

Watering & Establishment

Water regularly through the first summer, especially against a wall where soil dries fast. Established plants need water only in prolonged drought; potted plants need regular watering and a liquid feed through summer.

  • It is a selected form of the same species with pure white flowers instead of the usual blue and white banded ones. Hardiness, vigour and care are the same, so choose on flower colour. The RHS spells the cultivar 'Constance Eliott'; most nurseries write 'Constance Elliott'.

  • Yes. It is rated H4, hardy to around -10C, and grows outdoors in most of the UK on a sheltered, sunny wall. In a severe winter it may die back to the ground and regrow in late spring.

  • In mild areas it stays evergreen. In colder gardens it drops some or all of its leaves after hard frost and refurnishes in spring, so treat it as semi-evergreen.

  • Yes. Use a large container with a loam-based compost, an obelisk or trellis for support, and water and feed regularly through summer. Move the pot to a sheltered spot for winter.

  • The ripe orange fruits are edible but bland. The leaves and stems contain cyanogenic compounds and are listed as poisonous to people and pets if eaten, so keep the plant away from children and animals that chew.

  • 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.
