I went to Dalian,Liaoning Province few days ago.About August 26,I took some photo of the wild flower at Yanwoling Mountain,Dalian,which I have never seen before and can identify none.Could you help me?
Chinese plants the blue violet flower certainly is Platycodon grandiflorus, Balloonflower, related to campanulafamily
1st is suggestive of rubiaceae http://members.iinet.net.au/~weeds/western_weeds/rub_sal_sap.htm i'm sure you already noticed the 3rd looks like an onion (or related) the last looks like a campanula. maybe you can work out the likely exact species by locality?
