Does anyone know if it is possible to grow pine trees from pine nuts that are purchased in the supermarket? If yes, are there any tips on how to go about doing it?
Thanks

No the shell has been removed and they are old nuts. I have some fresh cones of Stone Pine Pinus pinea falling off the tree now, if you post a contact email I can post a few.

ps you need to pre treat the seeds of most Pines to germinate them(cold stratification) ie
The seeds of the Stone Pine have a relatively short natural dormancy compared to many species that needs to be broken down for germination to occur. If you do not pre-treat the seeds and simply sow them fresh, germination rates will be disappointing.

To break down the dormancy the seeds require a short period of cold stratification. To enable this the seed should first be soaked in water at room temperature for 24 hours. The water should be then drained off and the seeds mixed with a little clean, damp coarse sand or damp perlite and placed in a clear plastic bag (freezer bags are good!) at temperatures between 3-5 Celsius (37-41 Fahrenheit) which is about the temperature found in your fridge. Some variation in temperatures appears to be acceptable.

This pretreatment should last up to 8 weeks to ensure a well synchronised germination of the highest percentage. It is essential that the seeds are not waterlogged in the plastic bag or they may rot. After 4 weeks, check the seed every few days for signs of germination. Gently remove germinated seeds from the bag and plant them in a fairly deep pot containing a good quality seed raising mix. At the end of the pretreatment period you may sow all of the seed, even those that have not begun to germinate. Keep them at room temperature
