Description
Buddleja 'Flower Power', also known as Buddleja 'Bicolour', is a hybrid butterfly bush of modest size, with undeniable originality. Its clusters of purplish flowers opening in a beautiful soft orange and gradually turning to mauve-pink-violet cannot be ignored, as they create a fabulous two-tone spectacle with superb shading. This fully hardy variety blooms all summer, and even until October, covering its slender, bright green foliage with delightfully scented inflorescences. It thrives in ordinary, well-drained soil in full sun. It is truly magnificent as a standalone plant or planted in a flowering hedge.
Buddleja 'Flower Power' was born in the USA in 1999, created by Michael Dirr. An exceptional variety, it is the result of extensive hybridisation work between Buddleja x weyeriana 'Honeycomb' and the commonly found B. davidii species in our gardens. If you do not have a Buddleja in your garden because of its reputation as an invasive plant, this variety is made for you! Indeed, 'Flower Power', which is more drought-resistant than varieties derived solely from Buddleja davidii, forms a beautiful bush measuring 2 to 3 m (7 to 10 ft) in height and 1.5 m (5 ft) in width, with an open, arched habit and bushy vegetation from the base. It grows rapidly. It has the advantage of being sterile and therefore does not spread. It develops evergreen, opposite, ovate leaves measuring 4 to 5 cm (2 in) in length, with a slightly silvery greyish-green colour when budding, on upright, rigid branches. From July to September-October, it bears compact spikes, less than 25 cm (10 in) long, composed of tiny purple-violet flowers that change colour as they mature. They transition from violet to orange, displaying a whole range of intermediate shades along the spike.
It likes well-drained to dry soils, sunny locations, and shelter from wind. Remove faded flowers as they appear to maintain its appearance, and prune quite severely from March to April. There is no shortage of ideas to highlight this unusual buddleja, which is equally beautiful as a standalone plant or in a flowering hedge. In a shrub bed, it pairs well with shrubby cinquefoils, ceanothuses, tarentina myrtle, white buddlejas (White Profusion), or the silver-leaved Buddleja alternifolia. One can choose a harmony of warm tones to accompany it (orange, yellow, salmon-coloured repeat-flowering roses). Alternatively, highlight its complex colour with white flowers and silvery foliage (shrubby wormwoods, Helichrysum rosmarinifolium 'Silver Jubilee', Buddleja 'Silver Anniversary').

Planting and care
Plant in autumn, in well-drained soil, even chalky and poor soil, in full sun. Once well established, this bush will do without regular watering in summer, even in hot regions. Cut off faded flowers as they appear to maintain its appearance. However, this is optional.
Prune severely every year from March to April, on the previous year's growth, leaving 3 or 4 buds.
It may be prone to aphid attacks.

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).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
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 planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
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.
