I think your right Nutcutlet, bonariensis.
This could be a Sumach, they produce hundreds of new plants from their roots.
No 9 could be Golden Rod.
I'm glad it's not that. Was the only thing that appeared to be like the photo.
Looking in my pest book this could be Fireblight. If it is then you have a problem. Try googling it to get images so that you can compare.
Looks like an Aloe to me so surprised it's survive outside.
last months GW mag had an offer on lavender that is still open. 48 plants for just £5.60 postage
It's a teasel, wild flower that self seeds widely about.
Could it be a Silene?
Could someone please add me, I'm in Tadley Hampshire. Thanks
