If that were the case you would expect to see large growths of it in the wild, right? Whilst I do see it in the wild, I've never seen any situation where it looks to be taking over. I just see individual plants occasionally.
- rob74 2y agoMy reference for "highly invasive and spreads easily" is https://en.wikipedia.org/wiki/Impatiens_glandulifera#Invasive_species https://en.wikipedia.org/wiki/Impatiens_glandulifera#Invasiv..., which has by now completely taken over most clear and shady areas in and near forests where I live. Summer lilac is definitely far from being that bad. (I live in the South of Germany, but the UK, where it was originally introduced in the 19th century, seems to also have a huge problem with it: https://www.cabi.org/invasivespecies/species/himalayan-balsam/ https://www.cabi.org/invasivespecies/species/himalayan-balsa...)
- james-bcn 2y agoThat is not summer lilac. This is: https://vibrantgardenblog.wordpress.com/2016/12/02/buddleia-butterfly-bush-summer-lilac-easy-going-beginners-perennial-shrub/ https://vibrantgardenblog.wordpress.com/2016/12/02/buddleia-...
- jibbit 2y agofwiw the railway verges in london seem to be predominantly this - which also incidentally - i've never heard anyone call Summer Lilac before
- pvaldes 2y ago> I've never seen any situation where it looks to be taking over. I just see individual plants occasionally. Each one of those individual plants can produce 40.000 seeds each year, so give them a decade alone and you will see. Is very invasive on river beds and disturbed soils.
