Answer: Picea Glauca Conica is the botanical name for the miniature, cone shaped evergreen tree commonly known as the Dwarf Alberta Spruce. The foliage is compact and bright green, the needles are short and tightly placed.
Dwarf Alberta Spruce grows only 2 to 4 inches per year and reaches a mature height of 7 feet and width of 3 feet in 25 years. Because they are so slow growing, you can plant your trees closer than 3', but to allow good air circulation and good sunlight penetration, I'd keep them 3' apart.
