Buddleja tubiflora is

endemic to much of northern Argentina, southern Paraguay, and southern Brazil, where it grows at the edge of woodlands, thickets, and in old fields, at low elevations. The species was first named and described by George Bentham in 1846.[1][2]

Description

Buddleja tubiflora grows to < 2 m in height, with the typically lax habit creating a spread of < 3 m. The shrub is chiefly distinguished by its striking orange flowers, the

hummingbirds which feed on the sweet nectar at the base of the corolla. Ploidy: 2n = 38.[2]

Cultivation

Buddleja tubiflora is cultivated in the

NCCPG national collection at Longstock Park Nursery, near Stockbridge. The shrub can be grown on a south-facing wall in coastal areas of the UK, with added protection against frost, although waterlogging overwinter is considered a greater danger to the plant.[3] Hardiness: USDA zones 9–10.[3]
