May Plant of the Month | Raymond Evison Clematis
Clematis are stunning, versatile, long-lasting climbing plants that can brighten up any garden, whether positioned in a container, growing up a wall or fence or any other garden structure.
The beauty of Raymond Evison Clematis is in their keenness to perform with plentiful blooms along with their simplicity of care with most varieties needing only to be pruned hard back in late winter. While they are happy grown in the ground, they also perform particularly well in containers, making them suitable for the smallest of spaces or gardens with limited beds and borders.
We take a look at the history behind the award-winning Raymond Evison Clematis and offer advice on some best-loved varieties along with how to grow and care for your clematis.
Raymond Evison Clematis History & Expertise
Raymond Evison, born in 1944, started his horticultural career at the age of 15 in Shropshire and soon became Director of his first company, Treasures of Tenbury Ltd. A third of his stock was wiped out by a brutal winter, prompting him to move clematis operations to Guernsey where the climate is milder. He established The Guernsey Clematis Nursery in 1985.
For six decades, Raymond Evison has been searching for, breeding, and developing the world's best clematis. More than 100 Clematis varieties and cultivars have been developed and introduced by Raymond Evison, often seen at the company's gold-medal-winning RHS Chelsea Flower Show stands.
Breeding a new clematis is a long process, taking 10 years of crossing, selection, assessment and multiplication followed by continuous assessment for over 7 years before they are released to the market. New varieties are judged on their distinctive flowers, colour, growth, disease resistance, flowers per plant, and, of course, beauty.
Raymond Evison Clematis Varieties
There are an array of fantastic Raymond Evison Clematis varieties to choose from, but some of these are particularly versatile and perfect for growing in containers as well as in the ground.
Clematis Nubia™ Evipo079 was launched at the 2018 Chelsea flower show, a wonderful deep burgundy red flower with a dark centre. One of or if not the best container clematis varieties available.
Clematis Ooh La La ™ Evipo041 is a very compact and extremely free-flowering variety. It is best grown in shade where its brightly coloured flowers will lighten up a dark area. Equally at home either as a plant grown in a garden location or grown in a container on the deck garden, patio or outdoor dining area.
Cezanne ™ Evipo023(n) is perhaps the most vigorous in the compact patio range with a superb repeat-flowering habit. It is well suited for growing in a small garden as it only grows to about 3-4 ft. (90-120cm) in height. It produces early-season flowers then extension growth that soon produces multiple flowers, giving Cezanne a long flowering season. This variety is equally at home in a border or container on the patio or outdoor dining area where it flowers for a very long time. Its repeat-flowering habit is to be admired.

Raymond Evison Clematis Planting Ideas
Clematis love to climb, making them extremely versatile in the garden. A single variety grown alone in a large container can soon become a superb specimen brightening up a patio.
Equally, clematis trained across an uninspiring fence can transform it into a profusion of flowers throughout spring and summer.
Many people choose to grow several climbing plants together - either by combining clematis varieties or planting in combination with climbing roses, lonicera (honeysuckle), passiflora (passion flower) and more.
Clematis are superb grown up and over arches. Choose more vigorously growing cultivars and position one either side of the arch to be trained over.
