When cones are ripe seed is produced that can be planted in standard compost in med; size pots in shade. Keep cones indoors until they become dry, they will open, tap cones and pine nuts/seeds will drop out. They are not difficult, I have cultivated plants from gift shop painted Christmas cones, plant 1cm deep, and be patient.
