Geranium 'Brookside' – Award-Winning Blue Cranesbill

Geranium 'Brookside'

Widely regarded as one of the best blue-flowered hardy geraniums, Geranium 'Brookside' delivers a profusion of vivid, deep violet-blue flowers with white centers from late spring to midsummer, often reblooming in fall. Its dense, clumping habit features finely cut, bright green foliage that remains attractive throughout the season and shows improved heat resistance compared to older cultivars. An herbaceous perennial, it dies back in winter and returns vigorously each spring.
