Blue spruce

Short Description

The blue spruce is an evergreen conifer with a height of 15 to 30 metres. It has a conical crown.

The needles are rigid, strongly pointed and square. They are blue-green to silvery in colour with a wipeable blue-green coating. They are often slightly sickle-shaped (falcate).

The bark on the trunk is purplish grey or brown and coarsely scaly. The twigs are light to orange-brown.

There are male and female flowers. The male flower cones are yellow and often slightly tinged with red. They are located along the entire crown. The female cones are light pink to light red in colour and tend to grow in the upper part of the crown.

The elongated, conical cone grows up to eleven centimetres long. It is light brown. The cone scales are very thin and their edge is often wavy and finely toothed.

In the city

With its numerous cultivated forms, the blue spruce is very popular and one of the most frequently planted ornamental conifers. Especially the blue-grey variety is found as a solitary tree in many gardens and parks in the city. Occasionally it is also planted as a hedge. It is particularly suitable as an urban tree because it is insensitive to frost, drought and air pollution.
