This popular ornamental spruce can grow up to 150 feet and is native to the Caucasus Mountains and northern Asia Minor.
This species is prized for its gracefully pendulous foliage and for the young cones which are deep purple.
A grove of these trees can be found on the northeast side of the Pinetum.
2) Picea morrisonicola Taiwan Spruce
Endemic to the mountains of Taiwan, this spruce has slender, delicate shoots.
In its native range, this tree grows at high altitude from 6,600 feet to 8,200 feet above sea level.
The specimen in the Pinetum near the Newton Street entrance was grown from a wild-collected seed and has been part of the collection since 1958.
3) Picea engelmannii Engelmann Spruce
Native to western North America from British Columbia to New Mexico, this species is often grown for its blue-green needles.
Wood from young trees is used to make musical instruments including guitars, violins, and harps.
A group of these trees can be found in the Cascadia Forest at the south end of the Arboretum.
4) Picea breweriana Brewer Spruce
The long pendulous branches of this spruce efficiently shed snow in its native range in the mountains of southwest Oregon and northwest California.
There are about 35 species of Picea, and they are only found in the northern hemisphere.
A small specimen is located in the Cascadia Entry Garden.
5) Picea abies ‘Pendula’ Norway Spruce
This common European species is popular in cultivation with over 350 forms described. There are 15 forms in the Arboretum, many of them dwarf cultivars.
Scientists in Sweden have found a P. abies that is 9,550 years old – one of the world’s oldest trees. This tree, named Old Tjikko, has regenerated new trunks through clonal layering of branches. While each trunk lives only a few hundred years, low branches root into the ground and produce new trunks.
A large P. abies ’Pendula’ can be found at the south end of the Sorbus Collection.
