Picea pungens 'Blue Moon' / Blue Moon Colorado spruce

Picea pungens 'Blue Moon' is a dense, flattened globose form of Colorado spruce with robust, short, shiny Blue needles. It is a very diminutive cultivar that grows only 0.25 to 0.5 inch (1 cm) per year. After 10 years in the garden, a mature plant will be only about 10 inches (25 cm) wide and 8 inches (20 cm) tall.

This cultivar originated as witch's broom found in the early 2000s by Ruslyn Nursery, New Paltz, New York who introduced it to the nursery trade in 2005. It is sometimes seen listed as 'Ruslyn's Blue Moon.'
