Looking for Wood Stitchwort along the River Wye

Yesterday I went surveying Wood Stitchwort along the River Wye in Monmouthshire. This site is as close to the English border as you can get, only the bed of a dried stream separates the two countries. The Wood Stitchwort was on the Welsh bank of this stream, only five plants were found.  

Many fields along the River Wye were blue, these were fields of borage, not a crop I have come across in the UK before.

Fig-leaved Goosefoot (Chenopodium ficifolium) was one of the weeds of the borage fields.
