Salvia splendens, the scarlet sage, is a tender herbaceous perennial plant native to Brazil, growing at 2000 to elevation where it is warm year-round and with high humidity. The wild form, rarely seen in cultivation, reaches tall. Smaller cultivars are very popular as bedding plants, seen in shopping malls and public gardens all over the world.

Taxonomy: Salvia splendens was first described and named in 1822, when it was given the common name "Lee´s scarlet sage." Before dwarf cultivars were developed, an early Dutch selection known as ´Van Houttei´ was introduced and remains popular in the horticultural trade.

 The native type is rarely used or described, though it grew from in height. Its leaves are in even, elliptical arrangements, 7 × 5 cm, with dentate margin and long petioles. It may branch, where upper branches are finely hairy and lower parts hairless. Erect spikes of flowers sprout from the centre of the plant in groups of 2 to 6 from each leaf node; scarlet, tubular or bell-shaped, 35 mm long, with two lobes towards the apex; the upper lobe is 13 mm long. It flowers a good part of summer and autumn.

Cultivation: It is widely grown as an ornamental plant, with a large number of cultivars selected by different colours from white to dark purple. It is a subtropical species that does not survive freezing temperatures, but can grow in cold climates as an annual plant. The most common selections are the dwarf sizes that go by names such as ´Sizzler´ and ´Salsa´, and planted en masse in gardens and malls. ´Van Houttei´ reaches 1 to in height. The various types typically have red flowers.

Cultivars: Named cultivars include:
