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.
Delightful, golden-yellow flowers are borne in axillary clusters along reflexing stems from late summer into fall. Reliable, deep green, glossy foliage remains clean throughout the growing seasons. Not an aggressive runner, 'Solar Cascade' is a clump forming perennial reaching knee height, maxing out somewhere between the taller 'Fireworks' and more compact 'Golden Fleece'. Performs best in moist to average garden soil under full sun or partial shade; extremely drought tolerant once established. This great garden plant is easy to propagate and proved to be a standout in The Cincinnati Zoo and Botanical Garden perennial trials. Plant en masse for a dramatic effect or incorporate into seasonal arrangements.
Brilliant yellow flowers bloom in spring atop blue-green, pinnately lobed foliage. Leaf underside has a silvery cast. An easy-to-grow native that will self sow and form a dense shade groundcover. Tolerates all but the driest conditions. Beautiful paired with Mertensia virginica, Aquilegia canadensis, Aruncus dioicus, and Phlox divaricata.
