Big bears and the trees both thrive in the extremely harsh environments of the northern reaches of the world. Picea 'Chris Nova' was discovered in Hardiness Zone 6-b and has a deep yellow-green color and short needles. ×fennica, if the two taxa are considered subspecies); they differ from typical P. obovata from east of the Urals in having cones with less smoothly rounded, often triangular-pointed, scales.

The leaves are needle-like, 1–2 cm long, rhombic in cross-section, shiny green to grayish-green with inconspicuous stomatal lines; the leaves subtending a bud are distinctively angled out at a greater angle than the rest of the leaves (a character shared by only two or three other spruces). Having a very unique bluish green color, it is a pleasant sight in bleak, barren areas. Available: http://www.nature.com/hdy/journal/v74/n5/pdf/hdy199567a.pdf, accessed 2008.09.18. The species name is from the Latin term for "obovate," referring to the shape of the cone scales. Aljos Farjon (1990) described an intermediate form in northeastern Russia, Finnish spruce (P. × fennica E. Regel), witch represents an introgressive hybrid between the two species. They found so little variation between the two taxa, and such a large zone of introgressive hybridization (covering both sides of the Ural Mountains) as to warrant describing them as "two geographical races of one spruce species.".
Hardy to USDA Zone 2 — cold hardiness limit between -50° and -40°F (-45.6° and -40.0°C). Picea obovata, the Siberian spruce, is a spruce native to Siberia, from the Ural Mountains east to Magadan Oblast, and from the Arctic tree line south to the Altay Mountains in northwestern Mongolia. GROWTH SHAPE: Conical (Pyramidal) Although they only treat species cultivated in the U.K. and Ireland, and the taxonomy is a bit dated, still these accounts are thorough, treating such topics as species description, range, varieties, exceptionally old or tall specimens, remarkable trees, and cultivation. Synonyms: P. abies subsp. This series of volumes, privately printed, provides some of the most engaging descriptions of conifers ever published. Picea obovata with Betula sp. Hulten. Hi John, the picture didn't come across. RECOMMENDED HARDINESS ZONES: Very similar to P. abies, arguably synonymous or perhaps better described as a variety. Some authors describe this species as very similar to Norway spruce (P. abies), arguably synonymous or perhaps better described as a variety, Picea abies var. Picea obovata ‘Arctos’ is a befitting name of this Siberian spruce. ► are you sure of the species? This introgression is detailed by Krutovskii and Bergmann (1995), who analyzed isozyme loci for populations sampled from across the range of the two species. Refer to photo submittal. This introgression is detailed by Krutovskii and Bergmann (1995), who analyzed isozyme loci for populations sampled from across the range of the two species.

Despite being over a century old, they are generally accurate, and are illustrated with some remarkable photographs and lithographs. Introgressive hybridization and phylogenetic relationships between Norway, Picea abies (L.) Karst., and Siberian, P. obovata Ledeb., spruce species studied by isozyme loci. in Barguzimsky Natural Reserve near Baikal [Nikolai Nikolaevich Laschinskii, The Central Siberian Botanical Garden]. Picea obovata, as described in 1833 by Carl Friedrich von Ledebour (1785–1851), in Flora Altaica, 4th edition, is commonly known as Siberian spruce as well as Ель сибирская (Yel' sibirskaya) in the Russian language, 西伯利亚云杉 (xian bei yun shan) in Chinese, and Sibirgran in Norwegian.
Farjon, Aljos. The cones are cylindric-conic, 5–10 cm long and 1.5–2 cm broad, green or purple, maturing glossy brown 4–6 months after pollination, and have stiff, smoothly rounded scales. 42 m tall with a 150 cm dbh, on the Svyatoi Nos Peninsula, Lake Baikal, Russia.
