Description

Agapanthus praecox 'Zambezi' is the African lily at its most generous: broad, glossy evergreen straps of foliage all year, then tall stems in mid to late summer carrying great spherical heads of rich blue trumpets, each a firework of dozens of flowers that bees and butterflies work for weeks.

Evergreen agapanthus are the lush, big-headed side of the family, and the honest trade-off is hardiness: we rate 'Zambezi' H3. In mild and coastal gardens it overwinters outside under a deep dry mulch; everywhere else it is one of the great container plants, flowering harder for a snug root run and wintering under cover.

How and where to grow

  • Position: full sun.
  • Soil: fertile and free-draining; slightly pot-bound plants flower best.
  • Size: flower stems to around 1 m over 50 cm foliage.
  • Hardiness: H3; mulch deeply outdoors in mild areas, pot elsewhere.

Line a sunny path with pots of it, mass it in a coastal border where the salt air suits it, or grow it beside our other plants for pots. Compare it with the smaller Agapanthus africanus Blue and White we also grow.

Nursery-grown, well-rooted clumps. Overwintering honesty in our seasonal expectations guide.

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

What is Agapanthus 'Zambezi'?

An evergreen Agapanthus praecox selection with broad, strappy leaves and tall stems of rich blue trumpet heads in mid to late summer, each a firework of dozens of flowers. Evergreen kinds carry the lushest foliage in the genus.

Is evergreen agapanthus hardy?

Less so than the deciduous border kinds: we rate 'Zambezi' H3. In mild and coastal gardens it overwinters outside under a deep dry mulch; elsewhere pot culture with frost-free winter shelter is the honest route. See our seasonal expectations guide.

How do I get agapanthus to flower well?

Sun, summer feed, and a slightly tight root run: agapanthus famously flower hardest when their roots are cosy in a pot. Water freely in summer, high-potash feed fortnightly, and never coddle them with rich loose soil.

Is it best in a pot?

For most of the country, yes: a generous terracotta pot flowers magnificently, moves under cover in winter, and shows off the evergreen strap foliage year round. Companions in our plants for pots collection.

Is agapanthus toxic?

The sap and rhizomes are mildly toxic and can irritate skin and stomachs, so plant with gloves and discourage chewing pets. Handled normally it is a garden staple the world over.

Evergreen or deciduous agapanthus: which should I buy?

Deciduous kinds are hardier border plants; evergreen kinds like 'Zambezi' carry lusher foliage and bigger heads but want mulch or a pot in winter. We also grow Agapanthus africanus Blue and White for comparison.

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.
