은청가문비나무 '글로보사'-[정명]Picea pungens 'Globosa'

The blue spruce (Picea pungens), also commonly known as green spruce, Colorado spruce, or Colorado blue spruce, is a species of spruce tree native to North America in Arizona, Colorado, Idaho, New Mexico, Utah and Wyoming. It is noted for its blue-green colored needles, and has therefore been used as an ornamental tree in many places far beyond its native range.

Description

In the wild, Picea pungens grows to about 23 m (75 ft), but when planted in parks and gardens it seldom exceeds 15 m (49 ft) tall by 5 m (16 ft) wide. The tree can grow larger if the tip is cut when it is at least 3 years old. It is a columnar or conical evergreen conifer with densely growing horizontal branches. It has scaly grey bark on the trunk with yellowish-brown branches.

Waxy gray-green leaves, up to 3 cm (1 in) long, are arranged radially on the shoots which curve upwards. The pale brown cones are up to 10 cm (4 in) long.[5][6][7][8] Male cones are found on the entire tree, whereas the female cones are found at the top of the tree. This helps to facilitate cross-pollination.

The specific epithet pungens means "sharply pointed", referring to the leaves.

Ecology

Blue Spruce occurs at high elevation (above 6000 ft/1830m) in the Rocky Mountains of the west-central United States. It grows in mesic montane conifer forests, often associating with Douglas-fir, ponderosa pine, or white fir. It has a riparian affinity.

Picea pungens 'Globosa' is an extremely slow-growing spruce, which makes a wonderful mound of bobbly blue foliage, with tightly packed branches heading off in all directions. The needles colour-up best in full sun, and the effect is sensational in spring when new growth has a silvery blue sheen.

 

Grow Picea pungens 'Globosa' with contrasting plants such as heathers, or with vertical conifers. It has been given the Award of Garden Merit by the RHS.
