Philadelphus Pink Wins 2025 Chelsea Flower Show Prize

By Jill Brooke

Philadelphus Petite Perfume Pink (‘P1’) has been awarded RHS Plant of the Year 2025 at the Chelsea Flower Show. This recognition honors the work of Alan Postill, the breeder behind this variety, exhibited by Sparsholt College and supplied by Hillier Nurseries Ltd.

Petite Perfume Pink is the first truly pink-flowered Philadelphus to reach the market. Its deep pink buds open into beautifully scented blooms, with petals that soften to a pale pink on the outside and deepen to dark pink at the center, offering visual richness and powerful fragrance. With a naturally compact habit (H x S: 150 x 150 cm), it thrives in full sun to light shade and requires very little pruning – just occasionally to maintain its shape and encourage even more blooms. Petite Perfume Pink is an ideal choice for various types of gardens and landscapes.

Make sure to ask your nursery for this winner. The judges at the Chelsea Flower Show are not only experts but educators.

This recognition at Chelsea represents a major milestone for Alan Postill, whose expertise and dedication to horticultural excellence have brought a long-sought breakthrough to fruition. It also reflects the strength of collaboration between breeders, colleges, and growers in bringing innovative plants to a wider audience.

What we hope to do at FlowerPowerDaily is to showcase the best flowers and plants and also introduce you to the unsung heroes who work tirelessly to bring these flowers to the public. Alan Postill, has not only had 60 years of experience at Hillier but is considered one of the UK’s greatest plant breeders.

Since cultures share plants and flowers, expect to see these in the U.S. soon. Especially with the win at Chelsea Flower Show which is considered the most important flower show in the world.
