Handsome spruce. Is it growing near the P. toranos you posted earlier? Do they get supplemental watering or are they ”free range” as Ken would say? They look healthy and happy.
I don't know how tall your tree is c50, but in the link below I think I found a possible clue:
' A group of three grown from Priest 108, collected at Ejido do la Encantada, Zaragoza, Nuevo León in 1984, are particularly attractive; they were approximately 5 m tall when observed in 2005 but have since grown considerably, and produce a heavy crop of cones each year. '
So even if the 3 trees started producing cones at 5 m tall or after they 'grew considerably', it would still be apparent that they took at least 20 years to achieve the 5 m (16.4042 ft.) height and it was at that time or imo sometime later that cone production began.
