DistributionRead full entry
Range DescriptionLockwood (1973) formed the view that, despite the exclusive association of brugmansias with human habitation, native distributions of the species could be defined and recognised by the presence of intraspecific variability and high levels of fruit set, in contrast to low variability and low or absent fruit set in clones taken outside their native range.
On that basis the distribution is understood to be from south-central Ecuador to northeast Colombia. It is unclear if records from northwest Venezuela are of plants which are best regarded as native or introduced.
Despite occurring at relatively high altitude (2000-3000 m), this species is highly frost-sensitive, which may explain its absence from cooler, drier parts of the Andes at similar altitudes (Lockwood 1973: 52).
