Slow-growing tree that remains narrow when young but later grows asymmetrical and broad. The crown is semi-closed and more irregular than the species, and the lower branches, which are often shorter, hang down slightly. The trunk is purplish grey and smooth, but darker and peeling later. Twigs are bare, sometimes with fine hairs and greenish brown. The very twisted needles grow in bundles of 5 grouped primarily at the end of the twigs. This produces brush-like tops. The needles have a more striking blue colour than the species. Even young specimens already have hanging cones. Sometimes they grow singly, sometimes in groups. Tolerates sea wind, is suitable for planting in industrial areas, and requires a sunny site. Thanks to the decorate shape of the bluish grey needles, 'Glauca' is often grown in private gardens.
