RHS Chelsea Flower Show

RHS Chelsea Plant of the Year 2025

Celebrating exceptional new plants and highlighting the latest advances and emerging trends in garden plant breeding

This annual award celebrates outstanding plants with a new or improved feature, setting them apart from those already on the market. Floral exhibitors in the Great Pavilion were invited to submit new plants to the competition ahead of the Show. Entries were carefully considered by a shortlisting panel of RHS and industry experts, who whittled down the number of contenders to less than 20. These shortlisted plants then went on to be displayed at the Show where, on Press Day, members of our RHS Expert Groups viewed them and elected a winner.

The judges’ decision was based on three criteria: novelty and innovation, garden performance, and likely appeal for UK gardeners. The final vote is informed by the entry information submitted ahead of the Show, and the ‘wow’ factor of the plants on display.

These and all the shortlisted plants can be seen on the RHS Chelsea Flower Show Plant of the Year display in the Great Pavilion.

WINNER | Philadelphus PETITE PERFUME PINK (‘P1’)

Breeder: Alan Postill. Exhibitor: Sparsholt College. Supplier: Hillier Nurseries Ltd. Buy this plant >

The first truly pink-flowered Philadelphus. Deep pink buds open to fragranced flowers; the outside of the petals fading to pale pink with dark pink centres. Easy to grow, this unique mock orange’s compact nature means it requires no pruning and is ideal for any garden. Preferring full sun to light shade, this deciduous shrub is fully hardy in the UK. H x S: 150 x 150cm

Joint second place | Hosta ‘Silly String’

Breeder: Hans Hansen (Walter’s Gardens). Exhibitor: Sienna Hosta. Supplier: Fairweather’s Nursery. Buy this plant >

This hosta has narrow blue leaves with intensely wavy margins; a dramatic departure from the usual heart-shaped leaves. Vigorous and fast-growing, it forms a cascading mound of foliage with pale purple flower spikes in summer. Perfect for containers or the front of a shady garden. H x S: 35 x 70cm
