Dragon Spruce

Iseli Fastigiate Blue Spruce is perfect if you are looking for colour all year. A cultivar of the Blue Spruce, it is also known as the Columnar Colorado Blue Spruce. The Iseli Fastigiate Blue Spruce is one of the more distinctive evergreens. Its foliage is blueish in the spring and blue/green in the winter. Best used as an accent tree, the Blue Spruce has a narrowly upright and columnar form with upwards forking branches.

Dragon spruce is a unique looking spruce, as it is more shaggy and irregular than most spruces. They have sharp, stiff needles that are directed forward on the branch and their colour ranges from grey/green to blue/green.

They will grow in nutrient poor soils and can tolerate stronger winds, making them a good choice for providing shelter.

This species has been declining due to deforestation and related human activity in western China, its native range. It has notable genetic diversity for a spruce with a number of unusual growth habit variants. Given the cultural significance of the dragon, this tree should not be underestimated for its beauty or usefulness.
