Sakhalin Spruce

Sakhalin Spruce (Picea glehnii)

Sakhalin Spruce (Picea glehnii) is a rare, slow-growing evergreen conifer native to northern Japan and Sakhalin Island. Known for its rich green needles, compact pyramidal form, and reddish-brown bark, this species is prized by collectors and conifer enthusiasts for its refined appearance and adaptability to cold climates.

Distinctive Features

Picea glehnii develops a dense, conical habit with stiff horizontal branches and glossy dark green needles that are slightly curved and four-sided. New growth is vibrant and fresh in spring, maturing to a rich green that contrasts beautifully with its textured, reddish bark. Although it matures slowly, its symmetrical shape and tidy growth make it highly ornamental and well-suited for specialty gardens or small-space planting.
