Flowering: Flower buds appear already at the end of June. Blooming continues from July until the end of September. The small purple flowers, resembling lilacs, are gathered in very showy, long, cone-shaped inflorescences up to 40–60 cm in length. The flowers open gradually—first on the main shoots, then on the side branches. Thanks to its strong fragrance, the shrub attracts insects, especially butterflies.

Fruiting: Not applicable.

Growing conditions: Buddleja davidii ‘Ile de France’ requires warm and sunny locations. It grows best in wind-sheltered spots. Plant in fertile, well-drained soil with a neutral or slightly acidic pH.

Care: Do not water too abundantly, as the roots are sensitive to lack of air. However, watering is advisable during dry periods. This variety is frost-sensitive, so in late autumn, cover the base of the shrub with pine bark or leaves for winter protection. In spring, prune low to the ground and fertilize with a nitrogen-rich fertilizer. This encourages new shoots, maintains the shape of the shrub, and promotes abundant flowering. To prolong blooming, regularly remove faded flowers.

Use: Due to its lush flowering, Buddleja looks great in exposed locations. It can be planted individually or in groups. It is resistant to pollution, making it suitable for urban greenery.
