Description
Buddleja colvilei, or Colvile's Buddleia, made William Jackson Hooker exclaim "the most beautiful of all the Himalayan bushes" when he discovered it in 1849. This large bush or small tree bears the largest flowers of the genus, and undoubtedly the most spectacular. They resemble those of weigelas, sporting a deep pink colour illuminated by a white throat, and are gathered in large dense and trailing terminal spikes that bloom from top to bottom of the plant. Its luxuriant foliage resembles that of the medlar or certain rhododendrons. A very beautiful species, but not very hardy, to be reserved for gardens spared by severe frost. It also grows very well in a large pot, to be stored away from frost.
Buddleja colvilei is a botanical species with large development from the Scrophulariaceae (buddlejaceae) family. It is native to the eastern Himalayas (Bhutan, India, Nepal, Sikkim), where it grows in open and sunny places, between 1600 m and 4200 m (5249.3 ft and 13779.5 ft) altitude. In nature, it can form a small tree up to 9 m to 12 m (29.5 ft to 39.4 ft) high, carried by a single trunk. In cultivation, and in our favourable climates, it will quickly reach about 4 m (13.1 ft) in all directions, depending on the nature of the soil. Often starting from a single and short trunk, the flexible branches of this buddleia are pubescent and brown-purple in colour. They bear large entire leaves, ovate and elliptical, measuring 10 cm to 25 cm (3.9 in to 9.8 in) long. They are thick and deeply veined, downy when young, glabrous when mature. Their colour is a medium to dark green. Flowering takes place in summer, from June-July to September depending on the climate, for about 3 weeks. The pink and white bell-shaped flowers are gathered in spikes 15 cm to 20 cm (5.9 in to 7.9 in) long, which form on one-year-old wood. This slightly fragrant flowering gives way to small capsules measuring 1 cm to 1.6 cm (0.4 in to 0.6 in) in diameter. This bush does not suffer from occasional drought in deep soil.
Whether planted alone or in a group, in a hedge or at the back of a perennial bed, Buddleia colvilei will make its owner proud and enhance the garden or terrace, depending on the region. Plant with other shrubs to create a stunning display. Its summer bi-coloured flowering harmonises with shades ranging from white to purple, as well as dark foliage: Physocarpus opulifolius 'Summer Wine', Cotinus coggygria 'Velvet Cloak', Sedum 'Matrona', Hibiscus acetosella, or even a purple Phormium tenax will keep it company, being careful to place them in a sunny location. You can also plant it in a tall free hedge, on the boundaries of the garden. Gardeners in colder areas can welcome it on a terrace, as it adapts well to growing in large pots.

Planting and care
Buddleia colvilei likes fertile soils that remain fairly moist in summer. Plant in autumn in mild climates, or in spring in slightly cooler areas, in any well-drained, light, and fertile soil, preferably in full sun and in a sheltered position to improve its hardiness. You can plant it against a south-facing wall, as it can be trained very well. Avoid pruning it so that it can grow freely, produce flowers on its one-year-old branches, and form a small tree. If pruning becomes necessary, it should be done just after flowering, in early summer in mild climates. This will give the bush the opportunity to form branches that will flower the following year. It can be susceptible to attacks from red spider mites, and its foliage can be attacked by Botrytis in humid climates.
Pot cultivation:
In areas colder than -10° C (14° F), plant in a pot: choose a large container and pace it outside from May to September, in full sun. Water regularly to promote flower production. Prune after flowering to reduce the size of the bush so that it can be overwintered in a cool, very bright, unheated but frost-free room. Reduce watering, allow the substrate to dry between waterings. Fertilise in spring with a slow-release fertiliser for flowering shrubs.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
