Salvia guaranitica 'Black and Blue' is a selected cultivar of Salvia guaranitica, (now described as Salvia coerulea by The Plant List) and has large deep blue flowers with black calyces and attractive large-leaved strongly-scented foliage. A Salvia with strong woody stems it forms a large shrubby bush and flowers throughout the summer, often through until autumn. Its elongated deep blue flowers with their glossy black calyces are some of the most dramatic and visually-arresting of all Salvia flowers.

A warm sheltered aspect in full sun with a well-drained soil. Water well in the hot weather.

A bee-magnet.

This is my favourite Salvia. Highly recommended.
