The grapes are back (nearly)

Quite a few years ago I had an archway constructed as an entrance into our garden and my first idea was to grow red grapes up one side and white grapes up the other. So I duly planted said vines and waited and waited and waited and finally gave up and instead planted a beautiful climbing rose called Wedding Veil which rapidly took over the archway and does produce pretty white roses for about 10 minutes each year!  In the meantime the vines also began to grow and grow and grow!  The white variety have flourished much better and as can be seen by my blip last year we should be getting some beautiful grapes around October time!  Global warming has some advantages then?
