|Buddleja paniculata inflorescence|
Buddleja paniculata is endemic to a wide upland area from northern India to Bhutan, growing along forest margins, in thickets, and on rocky slopes at elevations of 500 – 3000 m. The species was named by Wallich and introduced to the UK in 1823 as seed sent by Major Madden from the Himalaya to the Glasnevin Botanic Garden.
Buddleja paniculata is a variable deciduous shrub or tree of bushy habit, occasionally reaching 6 m high. The sparse terminal panicles comprise white or pale lilac flowers, some forms pleasantly scented, others not, from December to mid-spring. The bright green lanceolate leaves are opposite, < 25 cm in length, and covered in fine hairs. 2n = 38.
Owing to its limited horticultural merit, B. paniculata is rarely cultivated. Moreover, it demands dry soils and frost protection overwinter. In the UK, it is grown under glass as part of the NCCPG national collection at Longstock Park Nursery, near Stockbridge. Hardiness: USDA zone 8.
