A trailing Bolivian begonia
Begonia boliviensis is a tuberous, trailing perennial grown for its arching stems and cascades of drooping, single scarlet-orange flowers through summer and autumn. It reaches a modest height and spread of around 60cm, making it a natural choice for pots and hanging baskets rather than borders.

From the Andes
This begonia's natural range lies in Argentina and Bolivia, and its name records that Bolivian origin. The 'Firecracker' selection is a further refinement of the species, bred for its slender orange flowers held in pendant clusters.

Light, moisture, and a warm start
Grow this begonia in full sun or partial shade, in loam or sandy soil kept moist but well-drained, at a neutral pH. Tubers are best started indoors in spring in light, free-draining compost, with 'Firecracker' preferring 16-18°C to get going, and plants can then move outdoors or into pots and baskets once frost has passed. It suits a sheltered spot and is only reliably hardy outdoors in a UK summer, so containers under glass or moved indoors for winter suit it best.

Cuttings, or seed
The species is propagated from basal or stem-tip softwood cuttings taken in spring or summer. 'Firecracker' can additionally be raised from seed, basal cuttings, or stem cuttings taken from sideshoots.

Angel wings and trailing stems
The species carries glossy, oval, pointed leaves in the classic angel-wing shape on arching, pendulous, succulent stems. 'Firecracker' shows pointed, toothed leaves to about 13cm long, and produces slender orange flowers to 5cm long in pendant clusters through the summer months.

A broad watch list
This begonia may draw caterpillars, mealy bugs, mites, glasshouse thrips, vine weevil, and aphids. None of these are unique to it, but they are worth checking for on the undersides of those glossy leaves.

Rot and mildew risks
The plant can be susceptible to grey mould, powdery mildew, stem rot, and rhizome rot. These issues tend to trace back to excess moisture or poor air movement around the succulent stems and tubers.

Dormancy and tidying
As the species dies back for winter, remove the old stems and foliage, then dry off the tubers and store them frost-free until spring. 'Firecracker' by contrast needs no pruning, though its tubers should still be lifted in autumn before the first frosts and dried off for the season.
