Gentian Sage (Salvia patens)
Description
Salvia patens (sometimes called gentian sage or spreading sage) is a herbaceous perennial that is native to a wide area of central Mexico. It was introduced into horticulture in 1838 and popularized a hundred years later by William Robinson. Salvia patens is tuberous, and easily lifted for overwintering in a greenhouse. The more common varieties reach 30–60 cm (12–24 in) tall and wide, and are covered with hastate shaped mistletoe-green leaves. Inflorescences reach 15 to 30 cm (5.9 to 11.8 in) or longer, rising well above the leaves. 2.6 cm (1.0 in) pure blue flowers are spaced along the inflorescence, with a 1.3 cm (0.51 in) green calyx that adds to the attractiveness of the flowers.
