Looks like Forsythia. Covered in yellow flowers in the spring. Prune after flowering. I have found it is very easy to root pieces of this, and have seen hedges done with it as well.

Yes it is forsythia and yes you can take cuttings . As Cinderella says ,normally the cuttings grow quite easily.

It's the biggest Forsythia I've seen! Crikey.....

Not sure if that is all Forsythia, but they do grow like that if not pruned back.

Thank you all for your helpful comments. We will be taking cuttings and hedging a part of our garden. :-)

Forsythia also puts out runners which can be cut off and transplanted to where you need them.
