if your thistle is onopordum giganteum i would say leave it-in my garden it comes up here and there, occasionally even in the right place but how wonderfully sculpural it is. in the last few weeks i have done my annual spring thinning and eradication of the overly enthusiastic-i think the close attention pays off in culture of the garden and if you keep all the spreaders out you lose so many chance and fugitive beauties-however i must say that phlox davidii is quite beyond the pale. emma crawforth if you read this what is the story about downloading pix, the site says no-is there some trick to it? i fogot to day that onopordum has occasionally reached 3 meters in my garden
