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.

The Guernsey Clematis Nursery Ltd is delighted to announce that Fenchurch Advisory Partners have generously agreed to sponsor the Raymond Evison Clematis Exhibit at the 2015 Chelsea Flower Show.

Raymond Evison OBE VMH has exhibited at the world famous Chelsea Flower Show for a great number of years and to date has been awarded 26 Chelsea Flower Show Gold Medals for exhibits that he has either grown the plants for, helped stage the exhibit and in the last twelve years design the exhibits as well.


Raymond Evison says: “The generous sponsorship provided by Fenchurch Advisory Partners allows us to stage stunning exhibits that would not be possible otherwise due to costs. In 2014 we were able to display our clematis in a very contemporary way, a great change to previous exhibits. In 2015 we will again exhibit our clematis in a similar contemporary way, which was so much admired by visitors to the Show and gained us great TV coverage thanks to the sponsorship”.


Malik Karim, Chief Executive of Fenchurch Advisory Partners says: “Raymond Evison has an outstanding and richly-deserved record at Chelsea and we are delighted to be supporting him again.”

Perfection is the name of the game for Raymond Evison when selecting new clematis plants.  Read more in this article -

Raymond Evison has achieved an amazing 25th Gold Medal at Chelsea Flower Show 2013, the 11th consecutive Gold. 

Raymond is very relieved as there was concern that the cold Spring would delay flowering.  He hopes all the visitors to this Centenary Show enjoy his exhibit in the Great Pavilion.


Chelsea Flower Show 2013



Preparations are now well underway for Chelsea Flower Show 2013 and there has been some welcome sunshine recently.  Due to the very cold Spring we had to force the summer flowering varieties under extra heat and also extend the day length by giving them extra light to encourage them to grow faster so they will flower for the show.  Here's a photo of the plants taken mid April.

Raymond constructed a wonderful display of clematis at the Philadelphia Flower Show in 2013.

We have many outlets selling our clematis in the USA and Canada.  Check out the list of garden centres here.

Which? Gardening have trialled clematis for gardens and we are delighted that the following Raymond Evison Clematis in particular were found to be in peak flower for weeks, well covered with flowers and kept to a good size and shape for growing in pots:

Chantilly - "best for rain resistance"

Parisienne - "best for two flower flushes"

Crystal Fountain - "best for neat plant"

Rebecca - "best for fantastic flower coverage"

Josephine - "best for vigorous growth"


Raymond Evison says "I spent much time visiting British garden centres this Spring and summer to give talks and meet the people who are growing our Raymond Evison clematis so successfully. I also visited Oregon, Seattle and British Colombia. It has been a difficult gardening year in North America with excessive rain and then summer heat. However, one of the most rewarding aspects of my visits was to learn how successful our brand plants are growing in people's gardens both in the UK and the USA.

"Everyone loves Rebecca because of its long flowering, deep coloured flowers but other, much spoken about clematis include Diana's Delight, Cezanne and the older Josephine. I hope everyone continues to enjoy their clematis and add to their collections."

Raymond Evison says “This is indeed a great honour.  I am aware of other people from around the world who have received this prestigious award, it came as a great surprise. To be selected by the PPA as the person from all over the world to receive this award for 2014 is truly something and a great accolade for our company on the island”.

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.
