This plant was raised by the wonderful Dutch designer Piet Oudholf and named for his wife. Sanguisorba ‘Tanna’ makes basal rosettes of handsome pinnate ash like leaves from which 40cm tall, wiry stems carry dozens of dark maroon bottle brushes. It has proved itself to be a pretty tough plant these last few years and gets by on minimal watering. Sun. 40cm x 30cm.
