Perennial sages look wonderful in ornamental borders, producing summer-long displays of spiky, nectar-rich flowers. Salvia nemorosa ‘Caradonna’ is a clump-forming salvia, bearing masses of violet-blue flowers from May to July.
For best results grow Salvia ‘Caradonna’ in a sunny, sheltered spot in well-drained soil. Deadhead spent blooms regularly to encourage flowers into mid-autumn. Mulch annually with well-rotted manure, or garden compost.
