Description

Buddleja speciosissima is a shrub 1 – 3 m high with light-brown fissured bark. It bears hermaphroditic flowers, unlike most South American members of the genus which are cryptically dioecious.[2] The young branches are thick, subquadrangular, and covered with a dense pale yellow indumentum, bearing subcoriaceous elliptic to lanceolate leaves with 1 – 3.5 cm petioles, and measuring 10 – 18 cm long by 2 – 4 cm wide, glabrescent above but tomentose below. The reddish-orange leafy inflorescences are 10 – 20 cm long, comprising 1 – 2 orders of branches bearing paired 3 – flowered cymes, the corollas 25 – 30 mm long by 4 mm wide, pollination being by hummingbirds. Ploidy: 2n = 38.[2]

The shrub is not known to be in cultivation.
