Plant of the month: Salvia elegans

Salvia elegans pineapple sage. Bright red tubular flowers with lime green leaves

Pineapple Sage is one of those plants that earns its place in the garden in so many ways. Its soft, lime green leaves smell just like fresh pineapple. And in autumn, it bursts into bloom with brilliant scarlet-red flowers that insects and birds love.

Native to Mexico, Salvia elegans inhabits pine-oak forests at elevations between 1,800 and 2,700 metres, which gives us a sense of its resilience. In Australian gardens it adapts well across a wide range of climates, from the cool tablelands of Victoria and New South Wales to the subtropical warmth of Queensland.

If you’re sensitive to smells, this is a great way to include some fragrance in your garden. Unlike some aromatic herbs that can be sharp or medicinal, the pineapple scent is sweet and clean. The leaves remain scented all year, and crushing them releases the fragrance.

Pineapple sage was used extensively in early traditional medicine by Indigenous Mexicans, who valued it for treating anxiety and high blood pressure. It also has genuine culinary appeal: the leaves have a pineapple fragrance and must be used fresh, as cooking destroys the scent. They work well in cold drinks such as fruit punch and iced tea, and in fruit salads.

If you're on a budget, this plant is a great investment. Cuttings take root easily, and a single purchased plant can quickly become many. It's also a generous wildlife plant, attracting butterflies, bees and honeyeaters when in flower.

Plant info

Botanical name: Salvia elegans

Common names: Pineapple Sage

Family: Lamiaceae

Type: Herbaceous perennial / subshrub

Origin: Mexico and Guatemala

Height: 1.2–1.5 m

Spread: 0.7–1 m

Uses: Herb garden, ornamental border, cottage garden, pots, edible garden, wildlife garden

Flowering time: Spring through to autumn, most prolifically in autumn as the nights lengthen

Flowers: Tubular, bright red, two-lipped flowers held in whorls of 6–12 at the tips of the stems

Growing notes

Light: Full sun to partial shade. In warmer climates, some afternoon shade in summer will reduce wilting on hot days.

Water: Requires regular watering and may wilt on hot days if water is lacking. Mulch well to retain moisture.

Soil: Prefers well-draining loamy soil that retains some moisture without becoming waterlogged. In pots, use a quality potting mix and ensure good drainage.

Care: Deadhead spent flower stalks to encourage more blooms. In frost-prone areas, cut back hard at the start of winter and it will reshoot from the base in spring. In frost-free areas, a hard prune in late winter keeps the plant shapely. Feed with a balanced liquid fertiliser during the growing season.

Propagation: Cuttings take root easily and will be ready for planting out in the warmer spring weather. Established clumps can also be divided. A perlite/vermiculite mix produces strong roots quickly; keep it consistently moist.
