blue black salvia

Salvia guaranitica (Anise-scented sage, Hummingbird sage) is a species of Salvia native to a wide area of South America, including Brazil, Paraguay, Uruguay, and Argentina.

It is a perennial subshrub growing 4 to 5 ft (1.2 to 1.5 m) tall, spreading into a large patch through its spreading roots. The leaves are ovate, 4 cm (1.6 in) long and nearly as wide, with a fresh mint green color, and an anise scent when crushed. The inflorescences are up to 25 cm (9.8 in) long with flowers in various shades of blue, including an uncommonly true blue. In cold regions, flowering begins in mid summer and continues until frost.
