Named by Klaus Jelitto of Jelitto Staudensamen (Perennial Seeds) in Germany, for Swedish nurseryman Magnus Nilsson, who carefully selected for ten years, looking for fine form, dark hue, and very horizontal petals. A tall, coarse plant with large, dark green leaves and a large, 3-4" flower with broad hot pink to purple petals that surround a brown/bronze cone. Plants are tough and heat and drought tolerant once established. Their roots have famous medicinal qualities, they make great, long lasting cut flowers and attract numerous butterflies and small birds.
