Pollyanna Wilkinson on Instagram: "Possibly my favourite grass of all time, Calamagrostis × acutiflora 'Karl Foerster' Grows in most soil types, (I grow it in clay with no issues at all) and best in sun or part shade. Use to add height in the border, or planted en masse to provide an ethereal, moving screen. It’s a deciduous grass but the skeleton gives gorgeous winter interest, so only cut down to ground level in spring. Tell me - Are you a fan of this fabulous grass?"
