Picea glauca ‘Densata’
This tree is found only the Black Hills region of South Dakota. It grows to 40 feet in height and 15 feet in width. It does not tolerate heat well and shouldn’t be grown south of Zone 6. It is considered to be a better ornamental tree than the straight species, Picea glauca, because it has a denser habit and brighter blue-green needles. It will do best in a sunny location with well-drained soil.
