Genus: Picea
Family: Pinaceae
There are about 50 species of spruce in the world, all in the Northern Hemisphere and half being from China. The spruce is a conical evergreen often with scaly bark. The leaves are needle-like and in many species are sharp at the tip. The cone sizes vary from quite small to very long, but they are usually pendulous and ripen in the first year.
Brewer’s Spruce
Scientific name: Picea brewerianaNative to the Siskiyou Mountains in California and Oregon at elevations of 5,000 to 7,000 feet, Brewer's Spruce is found only in a few small groves. Pendulous branchlets hang vercially 7-8 feet or more, creating a graceful curtain. This species was selected as a replacement from the original planting list.

Scientific name: Picea sitchensisNative to the Northwest, the Sitka Spruce is the largest of the spruce family and a fast grower. Its needles are very sharp and stiff, and its branches are long, growing from well down on the trunk, with an upward sweep at the end. The largest known Sitka Spruce in the lower 48 is found near Seaside, Oregon. Native Americans used this spruce to make baskets, rainhats, rope, tea, and chewing gum. We use it today for ladders, doors, oars, scaffolding, bleachers, boat masts, and musical instruments such as violins.
