| General Description | Picea pungens ‘The Blues’ is a weeping cultivar of Colorado blue spruce. It has blue and silver hued foliage and can reach heights of 2 m and spread up to 1.5 m. |
| ID Characteristic | ‘The Blues’ is easily identified by its vibrant hue of blue and silver and by the droopy, depressed foliage. The height of the spruce is also below 2 m, adding to its ease of identification. |
| Shape | This weeping Colorado spruce forms in a weeping/mounding/arching way, after being staked. Not much pruning is required other than removing die-back, but it can be trained into a desired shape. |
| Landscape | ‘The Blues’ makes an excellent specimen plant in any coniferous garden. This spruce must be staked at the desired height of its owner before letting it weep and mound. It can also be trained to become a bonsai or shaped as an accent tree. Due to its informal growth habits, it wouldn’t be well suited in a garden designed to be studious and uniform. |
| Propagation | Asexual propagation via grafting or softwood cuttings. |
| Cultivation | This spruce should be kept in a neutral to slightly acidic, well drained and moist soil. It is tolerant of salt, drought, and shade but should be given full sun. |
