Salvia buchananii is a herbaceous perennial shrub that isn't currently known in the wild, but is presumed to be from Mexico. Seed from a garden plant in Mexico City was taken to England around 1960, where it was grown by Sir Charles Buchanan. It is sometimes called Buchanan's fuchsia sage. It grows 1-2 feet tall and 1 foot wide, with glossy green leaves widely spaced along the stem. The flowers are a rich magenta, about 2 inches long, which rarely set seed.
