Picea pungens 'Blue Diamond', also known as silver spruce, silver fir or Picea pungens 'Christmas Blue', is a particularly popular ornamental conifer, valued for its intensely blue-silver needle foliage and its natural and elegant pyramidal shape.
Main Features
- Royal Color: The name "Blue Diamond" is perfectly justified. The needle color is an intense blue that adds a strong visual contrast to any landscape and remains equally vibrant throughout the year. The color intensity can be influenced by soil pH; more acidic soil tends to enhance the blue shade.
- Shape and Structure: It has a natural conical or pyramidal growth, very regular and dense, requiring little to no pruning to maintain a neat appearance.
- Size: It is a medium to large variety. At maturity, it can reach heights between 6 and 8 meters (although the growth rate is slow, about 10-20 cm per year).
- Hardiness: It is a robust, evergreen tree, fully frost-resistant (down to -40°C), adaptable to various climatic conditions in Romania.
Growing Conditions
- Light: Prefers locations with full sun to develop its optimal color.
- Soil: Adapts to most soil types, although some sources mention that more acidic soil can intensify the color, but it also tolerates calcareous soils. Well-drained soil is important.
- Maintenance: It is a low-maintenance plant, ideal for gardeners who want a strong visual impact with minimal effort.
Picea pungens 'Blue Diamond' is an excellent choice as a focal point in the garden, a solitary plant, or as part of a complex landscape arrangement, offering an air of refinement and structure throughout the year.
Indoor care conditions:
This fir is an outdoor plant but can be kept indoors during the holiday season provided it is placed in a cool area (e.g., a closed/open balcony), well ventilated, and watered when the substrate is dry. It does NOT tolerate high temperatures and lack of humidity well.
Height including pot: 130-140 cm
Pot diameter: 24 cm
Each specimen is unique and has a slightly different shape.
Note: The transport pot may become damaged/cracked due to the weight of the substrate and the plant. The growth type of the fir may vary depending on the batch and producer. Some specimens are grown directly in the pot, while others are initially grown in soil and then replanted into the pot.
