It is the herb Borage Kate. You can pick those flowers and freeze them in ice cubes or use them in a salad. The young leaves, they get hairy as they get older and the flowers have a slightly cucumber flavour.

The flowers are sometimes used to decorate a Pimms No 1!

Now your talking Melchisedec !!

Oh yes!

they are also nice in salads. the leaves taste of cucumber too.

thanks everyone ....Im off to buy Pimms :)
