Chelsea Flower Show 2026: The Plants You'll Want (And What They Cost)
Every year Chelsea drives demand for certain plants. Here's what's trending and how to buy before prices spike.
Chelsea Flower Show opens on 19 May this year, and if history is any guide, certain plants will be everywhere afterwards. Garden centres know the pattern well: whatever appears in the show gardens gets searched, shared, and sold out within a fortnight.
The trick, if you want those plants at a reasonable price, is to buy before the rush.
The Chelsea effect on prices
We tracked pricing data around last year's show and the pattern was clear. Plants that featured prominently in medal-winning gardens saw price increases of 10-25% in the weeks following Chelsea. Not because nurseries were gouging — most set prices months in advance — but because the cheapest stock sold first, leaving only the premium-priced options available.
Some plants simply sold out entirely. If you wanted a particular salvia cultivar last June, you were either on a waiting list or paying well above the spring price on secondary marketplaces.
The lesson is straightforward: if you already know what you want, buy it now. April stock is plentiful and prices are at their seasonal baseline.
What's likely to trend this year
Based on designer announcements, early show garden previews, and the general direction of UK planting fashion, here are the plants we expect to see everywhere after Chelsea 2026.
Salvias
Salvias have been building momentum for several years, and 2026 looks like the year they fully arrive. Expect to see Salvia 'Amistad' and Salvia nemorosa 'Caradonna' in multiple show gardens. Both are outstanding performers — 'Amistad' with its deep purple flowers from June to November, and 'Caradonna' with those distinctive dark stems that give structure to herbaceous plantings.
Right now, a 2-litre 'Amistad' costs between £8 and £12 at the nurseries we track. By late May, the cheaper end of that range will have disappeared. If you want several for a border scheme, April is the month to order.
Dahlias
Dahlias aren't new to Chelsea, but the palette is shifting. The trend is moving away from the brash dinner-plate varieties toward the darker, more refined types — 'Bishop of Llandaff' with its scarlet flowers against bronze foliage, and the increasingly popular 'Cafe au Lait' in soft peachy pink.
Dahlia tubers are remarkably good value in spring. You can buy a named variety for £4-£8 per tuber, pot them up now, and have flowering plants by July. Once they're sold as growing plants in 2-litre pots from June onwards, the same variety costs £10-£15. Starting from tubers in April saves you roughly half.
Ornamental grasses
The naturalistic planting movement continues to push grasses into mainstream gardens. Molinia caerulea 'Transparent' is a designer favourite — tall, airy, and genuinely beautiful when backlit by autumn sun. Stipa gigantea remains the go-to for structure, and Hakonechloa macra is likely to appear in any shade-focused designs.
Grasses are generally well-priced in spring, between £7 and £14 for a 2-litre pot depending on the species. They establish quickly from spring planting and most will be putting on a show by their first autumn.
Naturalistic perennials
Expect to see plenty of Sanguisorba, Knautia macedonica, and Verbena bonariensis — the loose, airy perennials that give that effortless, meadow-like feel. These aren't expensive plants individually (most sit between £6 and £10 in a 1-litre pot), but you need them in drifts of five or more to get the effect, so the total adds up.
Buying in bulk from a single nursery often triggers free delivery thresholds, which makes a meaningful difference when you're ordering fifteen plants at once.
How to buy smart around Chelsea
Order in April. Stock is at its broadest and prices are stable. Most nurseries dispatch within a week during spring.
Buy from specialists. A nursery that grows its own salvias will have better plants at better prices than a generalist reselling wholesale stock.
Don't panic-buy in June. If something sells out, it will be available again in autumn or the following spring. No plant is worth paying double for simply because it was on television.
Check our price comparisons. We track real-time pricing across UK nurseries so you can see who has stock and what it costs before you commit. A five-minute check can easily save you £10-£20 on a decent plant order.
Chelsea is a wonderful spectacle and a genuine source of inspiration. But the best time to act on that inspiration is before the show, not after. Your wallet will thank you.
