Borage is a herb that originated in Syria but grows naturally all over the Mediterranean. My mother used the young leaves to decorate her Pimms No. 1 Cup which she always served on Sundays before lunch.
Nowadays borage is commercially grown to produce 'star flower' oil - indeed, the plant is also known by that name.
In my garden it grows wild and seeds like crazy just about everywhere. As you see in the smaller photo, the tiny blue flower changes colour so often you have pink and blue flowers on the same plant.
