I would say it looks perfectly healthy!
It is putting roots out so you don't see much going on up top.
Plants take time to establish themselves,I am off out now to trim one of my pyracanthas as it is getting a bit big!!
As for buying plants at Asda or any other place,as long as they look healthy you have nothing to lose!
My garden is full of £1 clematis from Morrisons!
