Lechenaultia formosa, commonly known as Red Leschenaultia, is an evergreen subshrub native to the sandy plains and heathlands of Western Australia. It is a prostrate or erect shrub or subshrub with crowded, narrow, fleshy leaves and striking flowers that range in color from scarlet or orange-red to pale orange. This plant typically grows to a height of 20–40 cm (7.9–15.7 in) and has stems with many branches that may sucker. The leaves are 4.5–8.5 mm (0.18–0.33 in) long, contributing to its dense foliage. Flowering mainly occurs in winter and spring, but flowers can often be found throughout the year. The flowers are particularly showy, making it a popular choice for ornamental use.

Lechenaultia formosa is valued for its vibrant flowers and is widely cultivated in Australian gardens, often used in hanging baskets or rockeries. It was introduced to the United Kingdom in 1824, and although many cultivars were available in the 1960s, some are no longer in circulation. This plant requires well-ventilated locations with excellent drainage to prevent fungal diseases such as grey mould (Botrytis cinerea) and soil-borne pathogens like Phytophthora and Pythium. It is often short-lived if conditions are not ideal. Lechenaultia formosa thrives in full sun to part shade, with low water needs, and prefers soils with medium drainage. It is propagated readily from cuttings of semi-hardened wood, making it accessible for gardeners to multiply their plants.CC BY-SA 4.0
