As observed in cultivation, this fir has cones greatly variable in color – from green to purplish- or blue-gray. The length and color of the bracts are also variable. Most commonly the cones are dark gray with some level of bluish tint as shown in this specimen photographed in the arboretum of the Polish Institute of Dendrology (Kórnik).
