Spiraea douglasii

It's growing 😀

Mine have just started to flower 😉

This a quite young one and its in s very shady spot but I was told to be careful as they are very invasive, do you confirm that 😳 @fuschia

I have one in the back garden that has stayed relatively small infact I thought it had gone. It's under taller shrubs. I transplanted a piece into the front garden several years back and it is now about 6/7foot wide. It has taken over lots of my plants. However it looks fine as a hedge and has been that big for years. Hope that helps. 👍

Thank you @fuschia it does help, I'll keep a eye on this one 😀

Welcome 👍
