The cones of the fir tree, firmly fixed on the branches and standing like large candles, are hard to spot since they grow right at the summit of the tree. But the cones of the spruce hang from the end of the branches and fall to the ground when ripe. As for the leaves, the spruce's needles are slightly prickly, but not the fir tree's, which retain a characteristic deep green colour to the point of featuring on colour palettes as "pine green".
