Buddleja globosa
Encyclopedia
Buddleja globosa, also known as the Orange Ball Buddleja, is a species endemic to Chile
and Argentina
, where it grows in dry and moist forest, from sea level to 2,000 m. The species was first described and named by Hope
in 1782
shrub < 5 m tall, with grey fissured bark. The young branches are subquadrangular and tomentose
, bearing sessile
or subsessile lanceolate or elliptic
leaves 5 - 15 cm long by 2 - 6 cm wide, glabrescent
and bullate above and tomentose below. The deep-yellow to orange leafy-bracted
inflorescence
s comprise one terminal and < 7 pairs of pedunculate
globose heads, 1.2 - 2.8 cm in diameter, each with 30 - 50 flowers, heavily honey-scented.

, proving fairly frost-hardy in the UK. Unlike B. davidii, introduced over a century later, B. globosa is not invasive, owing to its dioecious nature, and wingless seeds.
