Salvia

Meet salvia, the flower that sets a bed on fire. Dense spikes of scarlet tubular flowers rise above dark green leaves, and the colour is doubled because the calyx behind each flower is as bright as the petals (NC State). Wikipedia notes that smaller cultivars are bedding plants seen in shopping malls and public gardens all over the world, and Dubai is no exception.

Dubai Municipality names salvia in its seasonal flower lists, and so does a 2004 Gulf News guide to the flowers of the season. In the UAE the plain name 'salvia' means this red bedding plant, which is why this page uses it, with scarlet sage as the English name.

Salvia is a warm-weather plant by nature, so it is one of the more forgiving of Dubai's bedding flowers in the shoulder months. It still asks for the cool season, and the guides agree that it fades as the heat arrives in April or May.

Salvia splendens is a tender perennial from Brazil that is grown as an annual (NC State, RHS). The flowers are borne in dense spikes, typically scarlet but also pink, purple, lavender and white, over oval leaves; plants are 30–60 cm tall and 20–40 cm wide, with compact bedding selections at the shorter end. UF/IFAS adds that salvias attract butterflies and hummingbirds and have no serious pests, though NC State cautions that many bedding cultivars have no nectar and are not a useful food for pollinators.

In Dubai it belongs to the cool-season rotation. Dubai Municipality's lists (Emirates 24|7, 2016; Al Bayan, 2020) name salvia among its seasonal flowers, Abu Dhabi City Municipality lists it among its winter flowers (Al Ittihad, 2020), a Dubai home-garden guide lists it among the annuals that do well from late October through winter in beds with at least half a day of sun, and Gulf News in 2006 included scarlet sage among annuals that can endure shade and semi-shade and hot, dry conditions. UF/IFAS says annual salvias are warm-season performers and NC State says it needs warmth, so it is less strictly a cool-season plant than petunia or pansy. The same guide says to expect it to fade as the heat arrives in April or May.

Care is about water and sun. NC State says it prefers full sun to part shade and well-drained soil and is not drought tolerant; RHS wants fertile, moist, well-drained soil and advises pinching out young growth to encourage a bushy plant. UF/IFAS warns that lighter-coloured annual salvias can be burned by high midday sun and do better with some protection, while darker colours resist sunburn better. Dubai's sandy soil drains well but holds few nutrients, so mix in compost and feed regularly.
