Picea pungens 'Jan Byczkowski' / Jan Byczkowski Colorado spruce

Picea pungens Jan Byczkowski is a dwarf, pyramidal selection of Colorado spruce with uniform, species-typical branching and nice blue foliage for most of the year. Each spring, for about 6 weeks, depending on how warm the spring is, the fresh new growth pushes forth in a stunning display of bright-yellow needles.

After 10 years of growth, a mature specimen will measure 4 feet (1.3 m) tall and 3 feet (1 m) wide, an annual growth rate of 4 to 6 inches (10 - 15 cm), a little slower than typically seen in the species.

This cultivar originated as a seedling selected by Jan Byczkowski of Poland.
