Used widely as a feature trees as well as privacy plant or screening tree, Picea Pungens or as it is commonly names, the ‘Blue spruce is aptly named for the wonderful blue green foliage color.
With horizontal branches and a pyramidical habit, Picea pungens can give a strong formal look to a garden when used as a feature tree.
Most species and cultivars are slow growing when first planted and seem to ‘speed up’ once the root system becomes established.
Pictured right we have Picea pungens R H Montgomery, a slow growing compact shrub. Over time ( around 10 years) reaching around 2ft with a spread of 3ft. Excellent dwarf form for growing in containers or in the garden. Well suited to the rock garden.
If planted in good soil, generally little extra care is required. Nearly all species and cultivars are regarded as suitable for USDA zones 3 – 7 with some suited to a wider growing range.
It is important to ensure reasonably good drainage. Additional water during the first few summers may be required.
Best grown in an open sunny position, in a cool to temperate climate.
