This plant (Buddleia davidii) is a member of the Loganiaceae family. It is nicknamed the "butterfly bush" due to its particular ability to attract a large number of lepidoptera, or also the "summer lilac".
Botanical description
This shrub is very resistant and grows quickly, with a tendency to spread out over a wide range. Its deciduous leaves, from 10 to 25 centimetres long, are opposed, finely dentated and spearheaded. Its flowers are small and look like lilac flowers. Short pods appear after the flowers are pollinated. These pods hold the seeds and stay in place throughout almost the entire winter.

Use
The buddleia is essentially a decorative shrub. If you plant this shrub, do not forget that some of its varieties, such as Buddleia davidii, are hardy and easy to grow, while other varieties are not, such as Buddleia colvilei! Remember to take the geographic location of your garden into account. If you choose a fragile variety, place it along south or west wall and protect it against the cold in winter. Do not fertilise this species, to avoid developing its foliage to the detriment of its flowers.
