This Buddleja is in the overgrown berries and wild cucumber, on the edge of the 'wilderness'. I'm sure that it's pretty old and must be B. davidii, which is allegedly invasive yet this is the only one that I've seen around, not another on the surrounding properties that I've seen. The first time I encountered B. davidii was in Washington many years ago. I did not know what it was, but saw a good stand of it (must be rather invasive there) on empty land and I quickly went home and grabbed a shovel, that was my first Buddleja (s)...lol...even there the stand was thick but not widespread.
So, I'm thinking that this year I wll grab seeds from this big one and sow them. I do have several Buddlejas that are sterile, but I want this one also and don't think it will be a problem...
Then there is this stand of Euphorbia...this is my big mound where I've been piling all of the dug-out sod, it's good topsoil...I also pile my waiting to be shredded prunings, etc there also and apparently some pulled Euphorbia ended up there....actually, I'm kind of liking it as a group and the bumblebees have been at them a lot, so they're staying there for now..
