Georg Arends was a German nurseryman who bred many perennial plants. His business was successful until the second world war and Rosa ‘Georg Arends’ and Rhododendron ‘Georg Arends’ are named after him.
Plants he bred include ‘Arendsii’ versions of Aconitum, Arabis, Phlox and Hosta sieboldiana. He also specialised in Bergenia breeding ‘Abendglocken’, ‘Morgenrote’ and the white flowered ‘Silberlicht’. (I was told Bergenia were called Elephant plants because an elephant could stamp on them and they would survive. However a more popular name is Elephant Ears after the leaves.)
