Callianthe megapotamica, commonly known as Trailing Abutilon, is a semi-deciduous shrub native to the Cerrado, a vast tropical savanna ecoregion of Brazil. It is adapted to a climate with a distinct dry season and is often found in open, sunny areas within this ecosystem. This species typically grows to a height of 2.5 meters (8 ft 2 in) and features leaves that are 5–8 centimeters (2.0–3.1 in) long, ovate to shallowly three-lobed. The flowers are a striking orange-yellow with a red base, each with five petals about 4 centimeters (1.6 in) long. They bloom prolifically from summer to frost, providing a showy display that resembles Chinese lanterns.

Trailing Abutilon is valued for its long flowering season and the vibrant color it adds to gardens. It is well-suited for use in subtropical gardens as a border plant or for adding vertical interest due to its height. The plant is relatively easy to maintain, requiring only medium amounts of water and thriving in soils with medium drainage. It prefers full sun to part shade, which encourages abundant flowering. While it is generally disease-resistant, it can be susceptible to pests like whiteflies and aphids. Pruning after flowering can help maintain its shape and promote vigorous growth. It is not known to be invasive but should be monitored to ensure it does not spread beyond desired areas.CC BY-SA 4.0
