Daphne bholua
Background and story
The Nepalese Paper Plant (Daphne bholua) is a semi-evergreen to evergreen shrub native to the eastern Himalayas, particularly Nepal and northern India, where it grows in woodland margins and mountainous terrain.
It was introduced to Ireland and Britain in the early 19th century, and has since become one of the most highly regarded winter-flowering shrubs.
It is especially valued for its clusters of intensely fragrant, tubular flowers, usually pale pink to white, which appear in mid to late winter, often when little else is in bloom, giving it both seasonal and sensory appeal.
Did you know?
Its scent can travel across an entire garden. The flowers are noted for an exceptionally strong, sweet fragrance, one of the most powerful among hardy shrubs and often detectable at a distance.
Hardiness and conservation
The recorded RHS hardiness rating is H4, which means this plant is usually hardy through most typical UK and Irish winter conditions, although exposed or wet sites can still cause losses. The recorded USDA/PFAF hardiness value is 7-10, which is useful as a broad winter-temperature guide, but it should not be read as a direct substitute for the RHS rating. Local hardiness always depends on local shelter, drainage, winter wet, salt-laden wind and the plant’s age and establishment.
The IUCN Red List status recorded here is Not Assessed (NA).
Additional notes for Ireland and Britain
In Ireland and Britain, Daphne bholua is moderately hardy but somewhat particular in its requirements, performing best in sheltered gardens with fertile, well-drained, neutral to slightly acidic soil. It thrives in full sun or light shade, and benefits from protection from cold winds, which can damage flowers and foliage. It typically grows to 2–4 metres, forming an upright shrub with a relatively open structure. While highly prized, it can be short-lived or difficult to establish, often resenting root disturbance, so careful siting is important from the outset. In favourable conditions, it is one of the most rewarding shrubs for winter interest.
From a conservation and hardiness perspective, Daphne bholua is not considered threatened, with a broad natural distribution across the Himalayan region, though local pressures on habitat exist. In terms of hardiness, it tolerates moderate frost (around −8°C to −10°C), though severe cold or exposure can reduce flowering performance. Its main limitations in Irish gardens are exposure, poor drainage, and root disturbance, rather than cold alone. In an Irish context, it is a highly desirable but slightly demanding shrub, valued for its exceptional winter fragrance where conditions suit it.
Notable features
- It flowers in the depths of winter. Unlike most shrubs, it produces its intensely scented flowers from midwinter into early spring, often before many deciduous plants have leafed out.
- It comes from surprisingly high altitudes. It grows naturally at 1,700–3,500 metres in the Himalayas, where it experiences cold winters, helping explain its relative hardiness.
- It has been used for paper-making for over 1,000 years. The fibrous inner bark is used in Nepal to produce lokta paper, a durable traditional paper still made today.
- It dislikes being moved once planted. Unlike many shrubs, it resents root disturbance and transplanting, which partly explains its reputation for being difficult to establish in gardens.
Earlscliffe notes
Daphne bhuloa, from the Himalayas, is a superb winter-flowering shrub here at Earlscliffe - good to look at and even better to smell. It begins to flower in December and continues until March, without showing any signs of frost or wind injury. Young flowers are purplish pink in colour and become white as the flower ages. The main attribute of Daphne bhuloa is the intense sweet fragrance from the flower clusters which can be smelt over a large area on a calm day.
