The team at Raymond Evison Clematis are very much looking forward to the 2018 Chelsea Flower Show.


The 2018 Chelsea Flower Show will see Raymond J. Evison OBE attempting to be awarded his 30th Chelsea Flower Show Gold Medal for exhibits of clematis cultivars.
He first exhibited at Chelsea in the late 1960s when he was a junior partner and managing director of Treasures of Tenbury Ltd, Tenbury Wells, Worcestershire.

Since 1997 he has exhibited from time to time from his Guernsey Clematis Nursery and from 2003 he has been awarded 15 consecutive Chelsea Flower Show Gold Medals.


The 2018 exhibit will be a contemporary seashore exhibit featuring clematis floating on 3 waves that are 14m long and also rolling underneath these waves.
There will be two board-walks where visitors can walk between the waves and admire the clematis flowers closely, thus interacting with the plants. Also incorporated in the design will be 5 boats full of clematis in flower, the boats will appear to be floating on a sea of blue clematis flowers along side the sandy shoreline .


The shoreline of sea sand  will feature amongst other items, old fashioned crab and lobster pots also enhanced  with clematis plants  in flower.
There will be three new clematis cultivars on view that are part of the Raymond Evison Clematis Collection for 2018, these being C.Nubia (tm) Evipo079(n) a stunning new red  C.Sarah Elizabeth (tm) Evipo098(n) a new colour break in pink flowered clematis, which is named after Sarah Elizabeth Groves who tragically lost her life in Kashmir .
And C.Tranquilite (tm) Evipo111(n) an outstanding very paleblue/white named to acknowledge the outstanding work of Les Bourgs Hospice in Guernsey.

Raymond's Guernsey Clematis Nursery is one of the leading breeders and producers of clematis in the world with over two million young clematis produced and shipped around the world during 2017, its new market areas include South Korea  Japan and China.

We are proud to annouce that Raymond Evison's 2017 exibit has been awarded with a Gold Medal. Raymond Evison's 15th consecutive gold.

The design featured Raymond Evison Clematis introductions draped in waves in a sea shore inspired design.  The adventurous design was acknowledged with the Design Innovation award for exhibits within the Great Pavillion.

At the 2017 Chelsea Flower Show Raymond Evison Clematis are featuring a Contemporary Sea Shore scene with clematis arranged to appear as if they were floating on 5 metal waves. Clematis will also be arranged under the waves in netting rolls as if they were left on the sea bed.
The exhibit is 140sq metres in area.
The base will be sea sand with some Guernsey beach pebbles and two wide broad walks where show visitors can walk between the waves and be able to interact with the clematis plants .
There will be over 2,000 plants displayed showing more than 40 different varieties of clematis, all bred in Raymond's famous Guernsey Clematis Nursery.

Three new Raymond Evison Clematis varieties are being released at the RHS Chelsea 2017 show.

C. Sachatm Evipo060 (n) .
A bright deep blue which is a marvellous multi flowering plant .
The flowers are produced in great abundance from early summer to Autumn, an ideal plant for any aspect or location, it grows to only 1-2/1-5m (4/5ft ) and is ideal for a small garden.

C. Charmainetm Evipo022 (n) .
A stunning scarlet coloured clematis which produces both single / semi- double and fully double flowers all at the same time on the same plant, each flower has a contrasting yellow centre. Flowering from early summer until early autumn .
Any aspect will suit this plant, (except north facing)but due to its heavy double flowers it is best grown through other wall trained shrubs or climbers where they will receive some protection from rain and strong winds.

C. Kittytm Evipo97 (n) .
A charming compact clematis that will only grows to about 60/90cm (2/3ft ).
It's creamy white flowers have a pinkish / brown centre and are only 8/9cm ( 4") in diameter,a repeat flowering plant from early summer to Autumn

Clematis Kitty is named in honour of an inspirational young women who was diagnosed with a rare form of Leukaemia when she was 14 years old.
The work of Anthony Nolan helped save her life .
When purchasing a plant of clematis Kitty, Raymond Evison Clematis will gift a percentage of their royalties to Anthony Nolan to help the charity to continue with its important and urgent work.

28th Chelsea Gold Medal and his 14th in succession.

Clematis VolunteerTM Evipo080 (n) ,has been named  Volunteer in recognition of the enormous work undertaken around the world by Volunteers .
The concept came from Jack Andrews himself a Volunteer at the Royal Botanic Gardens Kew ( England ) .
Jack and a team of Volunteers from RBG Kew will be present on the Raymond Evison Exhibit at Chelsea in 2016 .
.It is felt that the colour of the flower will lend itself to be purchased as a gift and grown by either male or female Volunteers ,a great way to recognise the valuable work carried out by Volunteers around the world .

Clematis TeklaTM Evipo069 (n) .
A very useful clematis for using with other plants in mixed borders ,through roses either growing up into them at the base of archways or free standing shrub or botanical roses giving them extra interest when they are not flowering ..
It's reddish /pink colouring lends itself beautifully to be used with a good cross section of other colours ,it associates splendidly with silver or golden variegated foliaged shrubs ,with purples and golden yellow foliaged shrubs such as philadelphus or weigela.

Raymond Evison Clematis are delighted to announce that Clema Corporation Watanabe Engei Japan have agreed to become a Raymond Evison Clematis brand grower for Japan.

Raymond Evison says that it is fitting that one of the leading clematis production nurseries in Japan has very kindly agreed to grow on clematis (for the Japanese market) that have started their life on the island of Guernsey.

The Raymond Evison clematis can be identified by the distinctive brand label, which carries Raymond's signature and will be available in leading Japanese retail plant centres.

Yuki Watanabe who visited Guernsey in the summer of 2014 says:

On behalf of Clema Corporation and Watanabe Engei, I am delighted to have become a Raymond Evison Brand grower for Japan.


It was over twenty years ago that we saw Mr. Evison for the first time.  We attended the lecture and demonstration given by him in Tokyo, Japan at that time, when we were deeply impressed by the clematis he bred.


It has been our dream, for a long time, to deal with his clematis at our company.  We have been engaged in growing and selling clematis for forty years.


In this fortieth anniversary year, we are delighted to have been given an opportunity to introduce the Raymond Evison Brand to the people in Japan.

Raymond Evison's award-winning clematis are proving popular in Russia.  For those of you who speak Russian, here's a link to a recent magazine article featuring an interview with Raymond.  Click here.

April 2012 has been as usual an exciting time in our breeding department as we have been selecting some most marvellous new clematis cultivars which will be offered on the market in a few years' time.  We and our Joint Venture Partners, Poulsen Roser A/S have been looking at the same cultivars both in Guernsey and Denmark and are delighted with the new selections, now the work begins on their propagation.  Chris and Dace have been helping Raymond Evison to choose the best cultivars.

Raymond J Evison Ltd. has been awarded the Royal Horticultural Society's Williams Memorial Medal for its exhibit of clematis plants at the Chelsea Flower Show 2010.  The award is granted to the best exhibit covering one particular genus of plants, out of any of the RHS shows, so the quality of competition is high.  This is the 6th time the company has won the award for a Chelsea exhibit.

In addition, Miss Maria Goncalves has been awarded the Mrs FE Rivis prize for her responsibility in growing the award-winning plants.

It's an exciting time selecting new breeding varieties.  Here Dace and Chris are picking out the best clematis and pollinating the crosses.
