Solidago 'Solar Cascade' (goldenrod)

Solidago 'Solar Cascade'

goldenrod

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.

goldenrod Interesting Notes

Solidago ‘Solar Cascade’ has delightful, golden-yellow flowers borne on axillary clusters along reflexing stems blooming from late summer into fall. Growing 24-30” tall and 18-24” wide, ‘Solar Cascade’ has reliable, deep green, glossy foliage that remains clean throughout the growing seasons and forms neat clumps in the garden. Selected by the Cincinnati Zoo & Botanic Garden.


It performs best in full sun to part sun in moist, gravelly, calcareous, well-drained soils. Plants spread slowly by rhizome and can spread by seed but require cross-pollination by a pollinator. They are self-sterile.


A wonderful addition for native plant gardens, pollinator gardens, or in the perennial border, plant ‘Solar Cascade’ en masse for a dramatic effect or to incorporate into seasonal arrangements. Primarily pollinated by the soldier beetle, the easily accessible flower clusters are beloved by many insects, from skippers to wasps to flies to beetles. We enjoy its compact height, standing between the taller Solidago ‘Golden Fleece’ but shorter than ‘Fireworks’.
