Buddleja paniculata is a species of flowering plant in the figwort family Scrophulariaceae, endemic to a wide upland area from northern India to Bhutan, growing along forest margins, in thickets, and on rocky slopes at elevations of 500–3,000 m (1,600–9,800 ft).
The species was named by Wallich and introduced to the UK in 1823 as seed sent by Major Madden from the Himalayas to the Glasnevin Botanic Garden.
[1] Buddleja paniculata is a variable deciduous shrub or tree of bushy habit, occasionally reaching 6 m (20 ft) high.
The sparse terminal panicles comprise white or pale lilac flowers, some forms pleasantly scented, others not, from December to mid-spring.
In the UK, it is grown under glass as part of the NCCPG national collection at Longstock Park Nursery, near Stockbridge.
