Butterfly Bush 'Flower Power' (Buddleja davidii) - nectar-rich shrub - 17 cm pot - Height 30 cm

Yes, Buddleja davidii 'Flower Power' is one of the most attractive plants for lepidoptera. Its long pinkish-purple panicles produce an abundant and accessible nectar thanks to the tubular shape of its small flowers, perfectly adapted to the butterfly's proboscis. Several species are regularly observed on a single bush at the same time: red admiral, peacock butterfly, swallowtail, lemon butterfly or common dormouse. This attractiveness is also explained by the intense fragrance of the clusters, perceptible from several meters away, which guides the pollinators.

The ideal time to plant the Buddleja davidii 'Flower Power' is in spring (March-April), once the risk of hard frosts has passed, or in autumn (September-October) to take advantage of the soil's natural moisture. Choose a full-sun location with well-drained soil. Dig a hole twice as wide and as deep as the root ball, loosen the bottom, incorporate some compost, and plant the plant so that the crown is level with the soil. Water thoroughly at planting, then maintain regular watering for the first few weeks.

The Buddleja davidii 'Flower Power' is a fast-growing shrub that can reach 1.50 to 2 meters in height in just a few seasons. Its growth rate is one of its most remarkable characteristics: in a single growing season, stems resulting from severe late-winter pruning can exceed one meter. Without regular pruning, the shrub tends to become bare at the base and produce lower-quality flowers at the top.

Yes, the Buddleja davidii 'Flower Power' is a fully hardy shrub adapted to the French climate. It withstands temperatures down to around -15 °C without protection, making it suitable for cultivation in almost all regions of mainland France. In very severe winters, the above-ground parts may be damaged or freeze completely, but the rootstock generally survives and regrows vigorously in spring.

The Buddleja davidii 'Flower Power' can be grown in a large pot or container on a terrace or balcony with plenty of sun. However, choose a container of at least 40 to 50 litres to allow it to develop its root system and flower profusely. Use a well-draining, slightly sandy potting mix, and make sure the container has good drainage holes. In a pot, watering should be more frequent than in the ground, as the potting mix dries out quickly in hot weather.

The flowering of the Buddleja davidii 'Flower Power' generally starts in July and can continue until October, meaning about three months of continuous flowering. This longevity is one of the shrub's great assets, as it extends the visual appeal of the garden long after other flowering shrubs have finished blooming. To encourage a second flush of flowers, regularly remove the faded flower spikes (a process known as deadheading): this stimulates the growth of new flowering side shoots.

The size of the 'Flower Power butterfly bush 'is reduced at the end of 'winter, ideally in March, just before the 'first buds appear. All stems should be cut back severely to 30 to 40 cm above the ground, without hesitation: a short pruning is essential to obtain long and generous flower panicles. If you prune too lightly or do not prune at all, the 'shrub quickly becomes woody at the base, sparse, and the quality of the flowers decreases significantly.
