I bought this from Peter at Bonsai Emporium in august last year. As you can see, it has now been in the bag for 12 months. I cannot remember what species it is
ID and advice would be greatly appreciated
Pinus halapensis - Alleppo pine would be my guess too. Allepos keep juvenile foliage like this for several years. Another possibility would be Pinus pinea - stone pine but it is usually a bit more blue.
I'm sure the nursery will be able to tell you what it is or at least give you the pine species they were selling around that time.
