Cephalaria radiata is a new species that we are trying in the garden this year. It is native to Romania and similar to the better known ‘Giant Scabious’ – Cephalaria gigantea with the same vigorous habit and wiry stems topped with large straw yellow scabious flowers in Summer. It is however a little shorter at 1.5 metres. I plan to try it in a reasonably generous space at the back of the border where it can clump up whilst producing an abundance of pincushion flowers floating above airy grasses. Recommended for naturalistic styles of planting and much loved by pollinators.
