Thanks will go have a look next week,

After some searching I also found these ones. Are they any good?

Chipchase Castle Nursery
clematis nursery in Beamish
Ryal Nursery
Longframlington
Hexham Herbs

Don't know about them. The best one [for us] has always been Halls of
Heddon, close to Heddon on the Wall: a very long-established and
'serious' nursery for all types of planting. You know where Heddon is:
about 10m West along the A69.
