Notes
'Radiance' cosmos (Cosmos 'Radiance') is an annual for borders, cut flowers, pollinator gardens, and cottage gardens. It cannot take cold, and a freeze will end its season. This plant likes full sun and dry to average, sandy, loamy, or clay soil. It grows about 47 to 59 inches tall and 12 to 24 inches wide. Butterflies and bees visit the blooms, and the plant is drought tolerant.
Pairs well with False Queen Anne's lace, ProCut White Lite sunflower, Hollyhock, and Red fescue.
