Lycett, who designed a royal flower arch at the show, said: "Adding stems of Clematis Amazing Oslo gives any decorating a lovely soft and "gathered from the garden" feel. I love working with them."
Amazing Oslo is on the market since early 2016 and is managed by Plantipp, which also manages Chelsea plant of the year Clematis' 'Amber'.
Peter van Rijssen, representative of Plantipp said: "We have noticed an increased demand for certain cut-flower varieties. Especially young consumers and leading florists want something different, special and on-trend. I am sure the Queen will enjoy her bouquet a few more days because this cut-flower Clematis has a long vase life."
