T&M is thrilled to announce that our entry Agapanthus 'Black Jack' has been crowned the RHS Chelsea Plant of the Year 2023. 

When four of our entries were shortlisted, we hardly dared to hope that one of these would take the winning spot. We are immensely proud to have scooped a hat trick of winners, with Hydrangea ‘Euphoria Pink’ in second, followed by Weigela 'Camouflage' in third. With some strong contenders in this year’s competition, this stunning achievement has been made all the more special. 


RHS Plant of the Year Winner


Agapanthus ‘Black Jack’

Larger and longer-lasting blooms produced in profusion!

'Black Jack' offers bigger flowers and more blooms through the season. This amazing Agapanthus produces 10 times as many florets per flowerhead for a flowering season twice as long as its competitors.

The “must have” Agapanthus for a striking display
Easy to grow and heat tolerant, 'Black Jack' boasts strong vigour and a striking presence in borders and containers. Large flowerheads are filled with black buds that open to deep black-purple striped blooms – these fade to deep purple and take on a dazzling metallic sheen with age

A unique variety from 20 years of breeding
De Wet Plant Breeders, South Africa, set out to produce disease resistant, vigorous, heat-tolerant and multi-flowering cultivars and a black cultivar was always high on the wish list. 17 years into the program, they finally got "the one"! 'Black Jack' is a unique Agapanthus that’s the result of years of dedicated hybridised breeding.

The first Hydrangea serrata that’s all about stunning foliage AND flowers!
The striking tricolour foliage of this handsome Hydrangea flushes vibrant pink, white and green each spring. As the pink fades, unique lacecap-style blooms burst from pale pink buds into two-tone red flowers with pale centres

Ideal for pots, containers & borders
This easy to grow shrub is ideal for moisture-retentive but well drained soil in sun or shade and is hardy down to -20C.

The latest in Hydrangea breeding
Hydrangea serrata 'Euphoria Pink' was discovered in a long-term Japanese breeding programme with rooted cuttings sent to Osco Garden BV in Aalsmeer, The Netherlands. Van Son & Koot Nursery BV from Kaatsheuvel / Netherlands rooted cuttings under license and prepared the plants for The Chelsea Flower Show.

Weigela 'Camouflage'

Vivid variegation plus bright red blooms!
‘Camouflage’ is a stunning compact Weigela with variegated bright green and dark black/green foliage. These petite plants become smothered with bright ruby-red funnel-shaped flowers borne on aching stems in May and June, attracting pollinators to the garden.

Sensational for small spaces
Weigela ‘Camouflage’ is a deciduous, low-maintenance, fully hardy shrub that’s perfect for small gardens and container growing. Grow in a sunny or semi-shaded position, in any well-drained soil.

From T&M’s own breeding programme
T&M’s Weigela breeding programme began in 2008 with the aim of producing compact plants with fabulous, coloured foliage, which are ideal for any size of garden. The programme continued until 2018, when selections were made from stock in the field and ‘Camouflage’ is the first in a series with variegated foliage.
