Abutilon megapotamicum

Abutilon megapotamicum prefers well-draining soil, regular watering, and a position with full sun to partial shade. It benefits from periodic pruning to maintain its sprawling or trailing habit and encourage new flowering growth. In cooler climates, it can be grown in containers and brought indoors or treated as an annual.

As a semi-evergreen shrub native to Brazil and Argentina, Abutilon megapotamicum is not reliably hardy in regions with freezing winters. It can tolerate light frost but sustained cold will damage or kill the plant. Gardeners in temperate zones often grow it in containers that can be moved to a protected location during winter.

The plant produces distinctive pendant flowers that resemble small Chinese lanterns, which is the origin of its common name. Each flower features a bright red calyx contrasting with soft yellow petals that emerge from within the red structure. The blooms hang from slender stalks and can appear over a long flowering season in suitable conditions.

The species is native to southern Brazil and Argentina, where it grows in warm, temperate to subtropical conditions. Its native range informs its preference for mild climates and its inability to withstand hard frost. The plant has been widely cultivated ornamentally well beyond its native South American range.
