Sorry, but Hawthorns are extremely difficult if not impossible to root from cuttings. You would need to take a piece and graft it on to a straight Hawthorn seedling.

Och! That's a shame Owdboggy - grafting is way beyond my capabilities. Thanks for taking the time to give a straight answers, saves me months of anticipation :)

No, sorry Snoop, Hawthorn just does not, under normal circumstances form root buds on the stems.
All the ornamental forms are grafted.

Such a shame it really is a beautiful colour. Just on the off chance, might it have produced suckers in at the base. I'm unaware of their growing habits but I suppose if they did it might be from the root stock, would that be right?
Sorry for so many questions.

If it is a self sown tree from a haw then it could produce suckers which would be the same as the parent tree. If it was grafted then yes any suckers would be from the rootstock.
Try collecting a few berries in Autumn and sowing them, you may get a tree like the parent, or maybe not.

Thanks Owdboggy, when I get more time I'll go round and have a closer look and collect some berries later in the year and see what happens.
