Notes
'Great Silence' dahlia (Dahlia 'Great Silence') is a perennial for borders, cut flowers, and pollinator gardens. It is hardy to USDA zone 8, or down to 10°F (-12°C). This plant likes full or part sun and average to moist, sandy, loamy, or clay soil. It blooms from early to late summer and again from early to late autumn. Butterflies, hummingbirds, bees, and birds visit the flowers. Cutting the blooms often can keep the plant flowering.
