Still a bit unsure Dove. Think they like alkaline soil whilst mine is acid?
am I right that sunflowers like alkaline too?
Geum TT is good call. I've got some so could have a go at propagating. Plus there's an apricot geum (mai tai I think) that I'm intending to get so fits the idea of not too many different types.
let me know re the verbascums as would like some if they could tolerate acid clay.
