RHS Plant of the Year 2023 Winner

Agapanthus ‘Black Jack’


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.

We’re also pleased to formally announce our partnership with Sparsholt College Hampshire on their Behind the Genes garden at RHS Chelsea Flower Show next month.

The garden, which is in the Discovery area of the Great Pavilion (Stand GPA154), offers a visually inspiring insight into the processes of plant breeding and explains techniques used to bring about improvements in plant species. Students at Sparsholt College have been involved in the design of the garden and have nurtured the plants that will be featured on the garden to illustrate various key milestones in plant breeding over the years.

T&M has long been at the forefront of plant breeding and can put its name to a number of key breeding breakthroughs over the years, such as Foxglove or Digitalis ‘Illumination Pink’ which won RHS Chelsea Plant of the Year in 2012 and which will feature on the Behind the Genes garden. Also appearing at RHS Chelsea 2019 is last year’s Plant of the Year winner, Hydrangea hybrid Runaway Bride® ‘Snow White’, and the amazing sunflower, Helianthus SunBelievable™ ‘Brown Eyed Girl’ which was placed third.

Part of the focus this year is also on our trainee manager, Lance Russell, who as an alumni of Sparsholt College, and now working at the forefront of the gardening industry, is the epitome of the new generation of inspiring and social media-savvy young gardeners. Lance is fronting our recent increase in film content on our website and YouTube channel and is set for a stellar career in horticulture. Lance can be seen in Thompson & Morgan’s video ‘Journey to Chelsea’.

‘Behind the Genes’

It’s a very exciting time of year. RHS Chelsea Flower Show preparations are in full swing and the countdown is on.

This year, Thompson & Morgan is teaming up with Sparsholt College who are creating a ‘Behind the Genes’ show garden which is diving into the science behind plant breeding and genetics to offer an insight into the development of plant breeding and selection.

'Behind the Genes' Chelsea Garden

T&M breeding is recognised around the globe and it’s a great opportunity to showcase some of this in the garden which has been designed by Sparsholt’s Chris Bird in The Discovery Zone inside the famous Great Pavilion. The garden will feature plants such as Hydrangea ‘Runaway Bride’, one of the most floriferous and vigorous hydrangeas which won first place in last year’s Plant of the Year competition and plants from our very own breeding programme, such as Helianthus ‘SunBelievable™ Brown Eyed Girl’ which won 3rd place in last year’s competition. This is the world’s first multi branching sunflowers which puts out over 1,000 flowers during the growing season.

My first trip to Chelsea was back in 2014 as a student at Sparsholt when we brought home the gold medal for ‘The Paper Chase’ garden and it’s great to be going back again this year with both my college and Thompson & Morgan to work on this very exciting project.

It’s a real honour to be a part of this project which aims to encourage the next generation of horticulturalists whilst promoting the opportunities that I’ve enjoyed – particularly at such a prestigious horticultural event! I’m hoping that by being involved in this garden, current Sparsholt students will be able to see the career options that await them.

A very busy few weeks lie ahead; preparing plants for Chelsea comes with its challenges. I find it’s almost like tricking nature, as you have to learn to sweet-talk plants to make them look beautiful on the day! Various methods are used to encourage plant growth, and in some cases, it’s necessary to ‘hold the plants back’.

Clematis ‘Kokonoe’ ©Plantipp/ Visions

Of course, the weather has a big impact on how well plants progress and as with all years, each season is different and no one can predict the weather.

Peter Freeman, our New Product Development Manager, has been working miracles and we have got some very exciting Plant of the Year entries that are being nurtured as I write, including a really striking, brand new clematis which has flowers that change shape throughout the season. Clematis ‘Kokonoe’ starts with warm purple single flowers which change into fully double pom-poms blooms as they develop to create a truly luxurious display!

We are also really excited to be joined by plant hunter Peter van Rijssen, who manages the trials for a worldwide portfolio of new plants and an avid promoter on social media of plants and new genetics.

I look forward to seeing you all at Chelsea!

Happy Gardening,

Green roofs: the only way is up

The top of Nic’s green-roof bin store in all its glory.

So your flowerbeds are full, the greenhouse is overflowing, there’s no more room for pots on the patio and every vertical surface in the garden is covered in foliage. How do you find space for new plants and enjoy the thrill of a fresh challenge in the garden?

The answer? A green roof bin store. As well as screening your unsightly plastic monstrosities from view, a custom-made green-roof bin store provides the perfect place to grow attractive, scented and edible plants for instant kerb appeal and a lasting first impression. Here’s how I designed mine…

How to build a green roof bin store

Nic’s bin store was inspired by this version in the RHS Community Garden at Hampton Court.
Image source: dogwooddays

Inspired by the RHS Greening the Grey Community Garden at Hampton Court Flower Show back in 2015, I fell in love with their fabulous bin store with a thyme and wild strawberry green roof.

Working with a local carpenter, I created my own version of a green roof store that would accommodate two bins and give me room to grow plants on the top and up the trellis sides. I also planned a selection of different sized holes in the side panel for solitary bees. Over the last three years these holes have been used regularly. I often see bees going in and out with their mud pellets blocking the holes.

Once the bin store was complete, I lined the top with heavy duty plastic sheeting and covered this with 20mm gravel to improve the drainage. I left a hole at the back through which the water could drain down a hose to the ground and screwed an upturned tea strainer over the hole to prevent blockages. I filled the rest of the top with a low-nutrient green roof substrate based on crushed recycled brick and green waste compost – and I was ready to plant it up.

Best plants for a green roof

Miniature succulents look stunning on a sunny ‘green roof’.

The bin store is in full sun, so I chose plants that prefer sunny, well-drained conditions like alpines, succulents and herbs. The sunniest side is filled with lemon thyme (Thymus x citriodorus) and Thymus ‘Silver Queen’, salad burnet (Sanguisorba minor), French tarragon (Artemisia dracunculus var. sativa) and winter savoury (Satureja montana). All have thrived and they are self-seeding on the roof, so I know that the conditions are right for them. Thrift (Armeria maritima) has also done well and self-seeds all over, but perhaps the most successful planting has been the succulents. I positioned them at the front so their delicate foliage and tiny flowers are at eye-level when I pass to empty the bins or get in the car.

In the spring, Sedum ‘Cape Blanco’ and Sedum spathulifolium ‘Purpureum’ have small starry yellow flowers and Saxifraga ‘Buttercream’ adds its soft milky flowers to the mix. During the summer months, Sempervivum arachnoideum sends up pink starry blossom spikelets and I grow annual climbers up the sides of the bin store – this year the trellis has been covered in the apricot shades of Thunbergia ‘African Sunset’ mixed with the deep purple bells of Rhodochiton atrosanguineum.

More than just a screen

Holes for solitary bees have been put to good use.

The bin store has been a practical success, but it’s added more than just a screen to the garden. I’ve been able to include plants which struggle in the shadier conditions of the back garden and bring some miniature succulent treasures into the limelight.

Although sedum matting is a great way to cover a green roof, if you’re hankering after extra growing room I’d encourage you to be ambitious and experiment with a range of species – perhaps herbs, alpines and different succulents, or even an elevated wildflower meadow – the sky really is the limit!
