Although Colorado spruce originates in the Rocky Mountains of Canada and the USA it has been in wide cultivation in Europe and its colder regions. In Czech Republic it has been a common jewel in front yards and small gardens for decades, especially its blue forms.
Description of the plant:
There are quite a lot of spruces called Blue. Blue Mountain is one of them. It is a selection with bright silvery blue needles. They are quite prickly, evergreen, and densely cover the branches. It grows about 15-25 cm per year when young, older trees grow a little faster. It is well branched from the base and forms a neat and regular pyramidal shape without any significant pruning. Trimming, however, is possible – best in early spring. Spruce is widely soil adaptable provided the soil is well-drained. It likes neutral to slightly acidic soil and full sun. No fertilizing is necessary. Fully hardy to about -40°C (USDA zone 3).
