This Giant Scotch Thistle stands majestically in the border at around nine feet tall and has just started to flower, which the bees will go made for! It is a biennial flower which will self seed readily. When I see the seedlings pop up I move them to where I want them to flower, usually at the back of a border where they are not going to attack passers-by (the leaves are very prickly!)
