Highbush Blueberries

[George the Pigman]

I got some small single bare rooted blueberries from Wilko several years ago and put them on my plot last year. This year two of them have grown huge! About 5ft high and the same wide. They have grey main stems and red/green mulltistems and so far I have no fruit. Are they rogue seedlings or the tall variety of highbush blueberries. Has anyone grown the latter?
