Picea glauca Conica - White Spruce

Picea glauca Conica is perhaps the most well-known and widely planted of the white spruces. This moderately growing conifer forms over time a perfect pyramid, covered with dense and naturally regular vegetation, giving it the neat appearance of a regularly pruned plant without any intervention. In spring, its young soft green shoots overwhelm the old foliage with a dark greenish-grey hue with blue undertones, composed of fine, short, and tightly packed needles. In the garden, it is a low-maintenance plant, as long as the soil it is planted in is deep and properly drained. 'Conica' is perfect for adding an elegant and slightly unique touch to the landscape, allowing for endless play with colours, vertical and horizontal lines, and textures. 

Picea glauca, also known as White Spruce or Canadian Spruce, is an evergreen conifer belonging to the pine family. It is native to Canada. In its natural environment, it grows slowly and has a fairly variable habit depending on its habitat, but is usually conical or pyramid-shaped with a wide base. This tree can reach a height of 25 m (82 ft). This species is traditionally used for paper production. It can live for many years (200 years or more).

The 'Conica' variety, derived from this species, is a dwarf and elegant form with a compact, conical, and upright habit. Very slowly, after about thirty years, it will reach 2 m (6 ft 6 in) in height and 1 m (3 ft 4 in) in spread, sometimes more in cool and humid climates. It produces short, ascending, and tightly packed branches, arranged in hierarchical and staggered patterns, covered with short, quadrangular needles that are very sharp and aromatic (with a pungent resin smell). They are covered with a white wax. Its spring shoots are a very soft green, and then its foliage takes on a slightly dull, uniformly green-grey hue, which varies depending on the plants. The root system of white spruces is shallow, highly branched, and spreading, making them difficult to transplant when mature and particularly sensitive to wind.

The 'Conica' white spruce, with its perfect habit, reduced maintenance, and ease of cultivation, is a perfect plant for rockeries, terraces, or individual planting. It thrives in many situations, in various climates, as long as the soil is well drained, deep, and not too chalky. This plant pairs well with large stones, geometric lines, and masonry works. It can be combined with dwarf conifers with a prostrate (Juniperus horizontalis Blue Chip), globose (Picea glauca Alberta Globe), columnar, or upright habit. The true graphic qualities of conifers naturally stand out in a contemporary garden, which emphasises shapes, silhouettes, and textures rather than the dance of blooms. These plants, with their reassuring permanence, provide lasting structure to a flower bed and mark pathways or the corner of a terrace, replacing the strong presence of trimmed boxwood or holly. They also pair well with heathers or ground-cover plants like aubrietas and ceraistes, as well as white-flowered shrubs like exochorda or mock orange. The key is to play with volumes and colours.
