Dublin Bay was introduced by Samuel McGredy IV in 1979, bred from two climbers with strong pedigrees: the pink Bantry Bay and the bold red Altissimo. That red character came through unmistakably. The blooms are semidouble and a deep, clear red with a mild fruity fragrance, carried on glossy medium-green foliage and canes studded with spines. Given adequate support, it will reach 12 feet tall on a spread of around 4 feet.

This climber suits any vertical surface where a season-long red presence is wanted, from a pergola post to a garden wall or a privacy screen. Full sun and fertile, well-drained moist soil suit it best. Prune for winter damage and size control in late winter to early spring, and remove diseased or damaged canes whenever they appear. Disease resistance is good overall, though deer will browse it without hesitation. A dependable performer for zones 6 through 9.
