The Guernsey Clematis Nursery Ltd regularly introduces new Evison®/Poulsen® cultivars to its range. All of these have been tested and assessed for 8-10 years in Guernsey and Denmark before reaching the market. We only introduce good healthy cultivars that flower prolifically over a long period and which have a long ‘shelf life’ for garden centres. They will provide flower at the critical time of the year for garden centres, ensuring maximum sales. They also repeat flower, allowing nurseries to programme their crop to release over a period of time.
