Picea mariana 'Nana'

Dwarf Black Spruce

Dwarf Black Spruce (Picea mariana ‘Nana’) forms a low cushion of fine, dusty blue-green needles. Closely layered branches create a soft-looking surface and a flattened silhouette that remains evergreen through winter.

Its slow growth makes it suitable for a rock garden or a carefully placed foreground accent. The plant broadens gradually and is most effective where neighboring shrubs cannot crowd its low branches. The ten-year size is an early growth guide, not a fixed mature limit.

Choose a cool site with a steady supply of moisture. Black spruce is poorly suited to sustained summer heat.
