    Buddleja colvilei is endemic to the eastern Himalaya ; discovered by Hooker in 1849, he declared it 'the handsomest of all Himalayan shrubs.'[1] In 1896 the species was awarded the RHS First Class Certificate (FCC),[2] given to plants 'of outstanding excellence for exhibition'.[3]

    Description

    B. colvilei is a deciduous large shrub or small tree which can grow > 13 m, often single stemmed. The flowers are arranged in drooping panicles, 15–20 cm long by > 8 cm wide, rose pink to crimson, but often white within the corolla tube. The flowers are among the largest of any in the genus, and appear in June. The leaves are < 25 cm long, narrow, shallowly-toothed, and tapered at either end.[1] This species has a high degree of polyploidy with a correspondingly high chromosome number of 2n = 152–456 (8x–24x).[4]

    Cultivation

    The shrub is not entirely hardy in the UK, and can only be reliably grown outdoors along the Atlantic coast.[1] Hardiness: United States Department of Agriculture zones 8–9.[5]

    Cultivars

    • Buddleja colvilei 'Kewensis', distinguished by its dark red flowers.
