New Plant Heritage Zone at RHS Chelsea Flower Show 2025

Plant Heritage returns to RHS Chelsea Flower Show where excitingly, two Collection Holders will exhibit for the first time. In the Floral Marquee’s Plant Heritage Zone visitors can admire stunning specimens from:

• Cornus, Newby Hall: A centrepiece Cornus kousa tree, underplanted with woodland herbaceous species, represents the plant diversity at Newby Hall in Yorkshire.
• Cosmos, Jonathan Sheppard: Following a successful first year at the show, Jonathan Sheppard is back for a second year and will launch new cultivars, such as ‘Fondant Fancy’.
• Digitalis, Terry and Mary Baker: This unique National Plant Collection celebrates the fabulous range of foxgloves.
• Iris (Bearded) and Paeonia (hybrid herbaceous), Clare Austin Hardy Plants: 25 bearded irises will showcase the development of flower form and colour over the past 100 years. Alongside them sits a selection of early flowering peonies, perfect for a late spring garden.
• Iris (Sir Cedric Morris Introductions), Sarah Cook: Flowers from this collection will be displayed alongside prints of the watercolour paintings from the Florilegium, showing the relationship between art and gardening.
• Rhododendron, Glendoick Gardens: Europe’s second largest rhododendron breeding programme will display new varieties at RHS Chelsea, including those bred for colour foliage, the latest evergreen azaleas and deciduous azaleas inspired by Scottish mountains.

The central Plant Heritage display (stand GPB020), the ‘Beauty of the National Plant Collections’, will have a selection of plants from National Plant Collections: two Geum collections – from Sue Martin in Kent and Maria Heffer in Bath; special Streptocarpus from Dibleys Nurseries in Denbighshire; Heuchera from Plantagogo in Cheshire, Lathyrus from English Sweet Peas and Roger Parsons and Baptisia from Daniel Simbrey in Essex. With a call to start a National Plant Collection, highlighted the 2025 Chelsea top missing collections.

Do come and say 'hello' if you are visiting the show - we'd love to see you. We'll have some seeds available too!
