Picea pungens 'Walnut Glen' / Walnut Glen Colorado spruce

Picea pungens 'Walnut Glen' slow-growing, upright pyramidal selection of Colorado spruce with foliage that flushes golden yellow in spring, then later fades to grayish Blue, frosted with golden highlights as the season progresses. Missouri Botanical Garden suggests that the variegated needles may suffer some scorch in young plants until they are well established. After 10 years of growth, a mature specimen will measure 5 feet (1.5 m) tall and and 2.5 feet (75 wide), an annual growth rate of around 6 inches (15 cm).

This cultivar originated as a unique specimen found by Vermont's Greg Williams growing in a private landscape in Walnut Glen, a subdivision of suburban Chester Country in southeastern Pennsylvania. He provisionally named the plant 'Goldie' in honor of the property owner, but later changed it to the name we use today. To this day, it is sometimes still seen listed as 'Goldie.'
