Blue Anise Sage 'Black and Blue'

Salvia guaranitica 'Black and Blue' | Also known as: Brazilian Sage 'Black and Blue', Giant blue sage 'Black and Blue', Sapphire sage 'Black and Blue', Anise-scented sage 'Black and Blue', Salvia concolor 'Black and Blue' | Rating: 0 votes | Print / Pdf

It would be difficult not to be taken by Salvia guaranitica. A bushy subshrub with foliage that has a refreshing, light green colour and aniseed scent, it is a highly popular option for borders or in informal gardens. But it is its brilliant blue flowers that it earns its reputation from. Known as the Blue Anise Sage, it offers a magnificent display when producing large, two-lipped blossoms on erect stalks. Plant in moist, modestly fertile or humus-rich soil in a sunny location, and since tender in its early years, it may need shelter and support. For pruning, deadhead faded flowers regularly.
