ZONES 2-8. One of our smallest and rarest of the Spruce family. Very tiny member of the white spruce family with 1/2-3/4" blue green needles. Reportedly hardy to Zone 1 when properly established in 2-3 years. That is minus 60 degrees F! Very slow growing to about 10" in 10 years but probably smaller. Untrimmed tends to spread wider. We have trained ours upright as mini trees. This is for the smallest of gardens, troughs, rock gardens, Bonsai and more as it takes a wide variety of weather. Very tiny white spruce with 1/2-3/4" blue green needles.
