Buddleja coriacea is a variable species endemic to the high Andes from the Cordillera Blanca in Peru to Lake Titicaca in Bolivia.
[1] Buddleja coriacea typically makes a densely crowned, sprawling trioecious shrub or tree, branching almost at ground level.
The scented inflorescences comprise 3–8 pairs of head-like cymes, 0.9–1.2 cm in diameter, of 8–12 flowers, the corollas 4.5–6 mm in length, deep yellow to orange-yellow, becoming orange-red with age.
[3] The shrub was introduced to horticulture in the UK circa 1994, and specimens are held as part of the NCCPG national collection at the Longstock Park Nursery, near Stockbridge.
[5] Although not entirely hardy in the UK, the shrub can survive most winters with a modicum of protection; overwinter waterlogging regarded as a greater danger to the plant.
