Picea mariana, the black spruce, is a North American species of spruce tree in the pine family. It is widespread across Canada, found in all 10 provinces and all 3 territories. It is the official tree of the province of Newfoundland and Labrador and is that province's most numerous tree. The range of the black spruce extends into northern parts of the United States: in Alaska, the Great Lakes region, and the upper Northeast. It is a frequent part of the biome known as taiga or boreal forest.

Picea sitchensis, the Sitka spruce, is a large, coniferous, evergreen tree growing to almost 100 meters (330 ft) tall, with a trunk diameter at breast height that can exceed 5 m (16 ft). It is by far the largest species of spruce and the fifth-largest conifer in the world, and the third-tallest conifer species. The Sitka spruce is one of the few species documented to exceed 90 m (300 ft) in height. Its name is derived from the community of Sitka in southeast Alaska, where it is prevalent. Its range hugs the western coast of Canada and the US, continuing south into northernmost California.

Picea engelmannii, with the common names Engelmann spruce, white spruce, mountain spruce, and silver spruce, is a species of spruce native to western North America. It is mostly a high-elevation mountain tree but also appears in watered canyons.
The blue spruce, 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.

Picea jezoensis, the dark-bark spruce, Ezo spruce, Yezo spruce, or Jezo spruce, is a large evergreen tree growing to 30–50 m tall and with a trunk diameter of up to 2 m. It is native to northeast Asia, from the mountains of central Japan and the Changbai Mountains on the China-North Korea border, north to eastern Siberia, including the Sikhote-Alin, Kuril Islands, Sakhalin and Kamchatka. It is found in cold but humid temperate rain forests, and nowhere does its range extend more than 400 km from the Pacific Ocean. The specific epithet jezoensis derives from Ezo, an old name for Hokkaido and other islands north of the Japanese island of Honshu, where the species is found.
Picea martinezii, the Martinez spruce, is a medium-sized evergreen tree growing to 25–35 m tall, and with a trunk diameter of up to 1 m. It is native to northeast Mexico, where it occurs at six localities in the Sierra Madre Oriental mountains in Nuevo León. It grows at moderate altitudes from 2150–2600 m, growing along streamsides in mountain valleys, where moisture levels in the soil are greater than the otherwise low rainfall in the area would suggest.
Picea chihuahuana, the Chihuahua spruce, is a medium-sized evergreen tree growing to 25–35 m tall, and with a trunk diameter of up to 1 m. It is native to northwest Mexico, where it occurs in 25 small populations in the Sierra Madre Occidental mountains in Chihuahua and Durango. It grows at moderate altitudes from 2300–3200 m, growing along streamsides in mountain valleys, where moisture levels in the soil are greater than the otherwise low rainfall in the area would suggest.

Picea koyamae is a rare spruce, endemic to the Akaishi Mountains and Yatsugatake Mountains in central Honshu, Japan. It is an evergreen tree growing to 25 m (82 ft) tall, with a trunk diameter of up to a metre. It grows in small isolated stands in a limited area and the total area of occupation is less than 100 square kilometres (39 sq mi). Trees that are lost to typhoons are normally replaced with other faster-growing species and the International Union for Conservation of Nature has rated the tree as "critically endangered". Some trees are in cultivation as an ornamental tree.
Picea smithiana is a species of evergreen tree in the family Pinaceae family. It is referred to by the common names morinda spruce and West Himalayan spruce, and is a spruce native to the western Himalaya and adjacent mountains, from northeast Afghanistan, northern Pakistan, India to central Nepal. It grows at altitudes of 2,400-3,600 m in forests together with deodar cedar, blue pine and pindrow fir.

It grows at elevations of 1,200–3,500 m (3,900–11,500 ft), usually in pure forests, sometimes mixed with the Tien Shan variety of Siberian fir. Its name was given in honour of Alexander von Schrenk (1816–1876).
