A bristly perennial plant, Borage grows on arable, disturbed places and is also found in gardens where it is cultivated for its leaves which have a cucumber like flavour. It stands to 60 cm high, and bears very pretty star-shaped blue flowers (20–25 mm across) in drooping, loose, leafy clusters from May to September. The five petals are narrow and backward pointed, the dark sepals appearing between them, and at the centre of the flower is a column of purple-black anthers grouped together and projecting. The leaves are pointed with wavy margins, the lower ones stalked and the upper clasping the stem. This is a garden escape which becomes naturalised on occasion. It belongs to the Boraginaceae family.
My first record of this plant is from the railway line at Killiney, Co Dublin. At one time there were few trains on this line on Sundays and it was safe to walk along. Now, with the regular traffic of the DART (Dublin Area Rapid Transport), there are no opportunities for walking the line, looking for wildflowers. Coincidentally, this plant was listed in Nathaniel Colgan's Flora of Co Dublin (1904) in which he wrote: 'Several plants by the railway at Vico, Dalkey, 1901-2 ... a garden outcast' . I took these photographs near Kilmore Quay, Co Wexford in 2008.
