Two "Successes."?

      One by accident; one by design.  The design first - The Thornless "Blackite" which appeared in a corner of the back Garden a year or three ago.  I took one of its Runners and "stolonised" it successfully.  SO - I can now surgically remove the parent Plant.
      You can't see too clearly and I've yet to count them, but I suspect half a dozen or so shoots are likely.  I will count them - eventually.
      The accidental next - Right beside it you might see a Sycamore "Helicopter" standing to attention, with root poking out the bottom.  The nearest "wild" Trees are a minimum of 50 yards away, with NO idea of their species.
