Buddleja nivea var. yunnanensis is a vigorous shrub endemic to the province of Yunnan in China, where it was discovered by Wilson. It was conferred varietal status by Alfred Rehder and Wilson in 1913,[1] but later sunk as simply Buddleja nivea by Leeuwenberg[2]

Description

The distinction of var. yunnanensis was largely a matter of scale; its leaves and inflorescences all larger than the type. The shrub can rapidly achieve a height of 4 metres (13 ft) in cultivation, and like the type its young growth is covered by a white indumentum. The ovate-lanceolate leaves are of great size, 50 centimetres (20 in) long, but less felted than B. nivea.[1]

Cultivation

The plant can still be found under its old varietal name in specialist collections in the UK. A large specimen is grown as part of the NCCPG National Collection held by Longstock Park Nursery near Stockbridge, Hampshire.

gollark: MEDDLING WITH THE VERY FABRIC OF TIME ITSELF is not an appropriate way to give people more time at some times.

gollark: Not really!

gollark: * is really bad

gollark: I can also just hit a keyboard shortcut to pull up a shell and type in "date".
