ABUTILON megapotamicum ‘Red Trumpet’®

Native to South America, Abutilon megapotamicum ‘Red Trumpet’®, commonly known as trailing abutilon, stands out for its graceful, arching habit and its long-lasting bicoloured lantern-shaped flowers.

Characteristics of Abutilon megapotamicum ‘Red Trumpet’®

This abutilon forms a well-branched shrub with long, arching stems that can be trained against a support. Its mid-green, heart-shaped and slightly toothed foliage remains evergreen in mild climates but may become deciduous following a cold spell. The pendulous flowers feature a swollen, bright red calyx surrounding yellow to orange petals, producing the distinctive appearance of a hanging lantern. Flowering continues for several months when the plant benefits from warmth, good light and regular feeding. Its limited hardiness means it should be planted in a sheltered position or overwintered in frost-free conditions in colder regions.

How to use Abutilon megapotamicum ‘Red Trumpet’®?

Thanks to its flexible stems, ‘Red Trumpet’® can be trained against a warm wall, trellis or small pergola. This growing method highlights its pendulous flowers while protecting the plant from cold winds. In coastal climates or sheltered urban gardens, it can be planted directly in the ground within an exotic or Mediterranean-style border. In colder regions, growing it in a large container is preferable, allowing it to be moved into a greenhouse, conservatory or bright frost-free room for winter. It can also be trained as a standard to create an attractive specimen plant for terraces and patios.

What are the best cultivation tips for Abutilon megapotamicum ‘Red Trumpet’®?

Plant it in fertile, humus-rich and well-drained soil, in non-scorching sun or bright partial shade. When planting in the ground, allow approximately 1.20 m between plants and choose a sheltered location, ideally against a south- or west-facing wall. Water regularly throughout the growing season, without allowing water to stagnate around the roots. An organic mulch will help retain soil moisture. Apply a balanced fertiliser in spring, followed by a flowering plant feed during summer. Prune lightly at the end of winter to remove weak wood and encourage branching. Protect the plant or move it indoors when temperatures approach -5°C.
