Buddleia davidii

Who would think that this plant with its delightful name would become an environmental weed?

Arching stems carry sprays of tiny gold throated, mauve flowers in spring and summer and is attractive to butterflies.

It was also very popular as a quick growing privacy plant, however there are now many better, non invasive alternatives.



  • Seeds are spread by wind and water.
  • Dumping of garden prunings that may easily take root.
  • This plant grows readily in damp areas to create shady thickets crowding out natural species and destroying habitat.

Remove these plants from gardens and choose superior species from others that will prove more environmentally friendly while at the same time still attracting butterflies
