Salvia ‘Carolus’ presents a profusion of lilac flowers complemented by aromatic green foliage. Once established, it displays tolerance to drought conditions. While generally expected to withstand UK winters, it may benefit from protection in the face of severe frost. Well-suited for both pots and borders, ‘Carolus’ is an attractive choice that draws in bees and butterflies with its nectar-rich flowers. This variety was bred by Marc Vanlancker from Oudenaarde, Belgium.
