Dwarf Black Spruce

Picea mariana 'Nana'

A standout in the rock garden, forming an attractive broad dense globe of lovely blue-green needles. A very slow growing evergreen that will require little to no maintenance. A great filler between larger trees and shrubs. Works well en masse in borders and along driveways, or as a single accent in a rock garden.
There are very few rules in gardening, but perhaps the most important one is to work within your zone. Choosing plants that grow and thrive in your particular climate is the very first step toward having a beautiful garden . Learn More
