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.
