Early days

Born in 1944, Raymond Evison started his horticultural career at the age of 15 in Shropshire and quickly became the Director of his first company: "Treasures of Tenbury Ltd". A brutal winter killed a third of his mother stock and he moved the clematis operations to Guernsey, in the sunny Channel Islands near France where he set up The Guernsey Clematis Nursery in 1985, to take advantage of the milder climate and long growing season.

Production at the Guernsey Clematis Nursery

These glasshouses have been upgraded to state of the art facilities and the nursery now produces 2-3 million young plants per year and exports to 20 countries worldwide.
