What is this please????

Looks like a variety of solidago (Golden Rod)

Yes it looks like it to me too! it can spread so be careful - I have some in my garden and the hoverflies and bees love it.

Thank you Andrew....I noticed a lot of bees around it Olive...I was hoping i would remember when someone told me the name......but, no recollection whatsoever.....

Sounds a bit like my memory that Moti. lol. don't worry about it, I put mine down to having too many plant names to remember. I shall have forgotten by tomorrow and will need to rack my brain to remember lol.

Thank you for that Olive....I'll be careful this doesnt spread...im glad you told me....:>)
