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. Blue Diamond is a variety that originated in Deurne, the Netherlands, in 1990 as a hybrid between picea pungens Glauca and picea pungens (seedling). After more than 20 years of testing and reproduction its main features proved stable and the plant was patented both in Europe and the USA (PP19,550). Its reproduction without license is prohibited. Introduced to the green market in 2006.
Blue Diamond is a true jewel. This conifer is a variety of Colorado spruce with intensely blue coloured needles with silver overlay. They are quite prickly and evergreen. It grows about 15 cm per year, and only 10 cm upwards making about 1m tall plant in 10 years time. It is well branched from the base and forms a neat and quite regular pyramidal shape without any significant pruning. Trimming, however, is possible – best in early spring. Mature plants are expected to reach about 5m or a little more under ideal conditions.
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).
