Suttons’ Sedum Atlantis takes the coveted title

One of the most eagerly anticipated parts of the Chelsea Flower Show is seeing which new plants* are introduced – and the winner is Sedum takesimense Atlantis (Nonsitnal), from Suttons – congratulations!

It’s drought-resistant and easy to care for, ideal for our changing climate. An attractive, easy to grow, versatile and multi-functional plant, it forms 30cm high cushions of variegated foliage topped with yellow flowers from June to September.

The cultivar was discovered as a sport on a nursery on the banks of Lake Michigan by grower Dave Mackenzie, who specialises in plants for ground cover, green roofs and walls.

Available from Suttons, it can be seen in the Great Pavilion on the stand of the National Dahlia Collection.

Second-placed plant

Taking second place is Digitalis x valinii Firebird bred in the UK by Hardy’s Cottage Garden Plants. It has 90cm flowering spikes of warm reddish-pink with apricot tones from May to October. A reliable perennial, it has a branching habit and is also attractive to pollinators.

Third-placed plant

The third spot was taken by Agapanthus Fireworks from Thompson & Morgan.

The evergreen perennial has large umbels of bicolour flowers displaying rich blue bases and white flaring petal tips from July to September.

Growth is strong but short and clean and plants are suitable for containers or growing in garden borders.

*Information and pictures provided (or not) by exhibitors. Plants are either new hybrids, new to the UK market or being seen for the first time at Chelsea.

Winners in 2018

Last year’s winner was Hydrangea Runaway Bride Snow White, exhibited by The Sun newspaper with Thompson & Morgan, bred by Ushio Sakazaki, a hybrid of a remote Asian species with H. macrophylla producing lots of lace-cap flowers with a graceful trailing habit.

In second and third place came Eryngium Blue Waves and Helianthus annus Sunbelievable Brown Eyed Girl.

Plants are judged by a panel of RHS experts including the director of horticulture, RHS Plant Committee chairs and curators of RHS Gardens, assessing each variety on its innovation, appeal, excellence and impact.
