Abies concolor ‘Piedra’

Abies concolor 'Piedra' #5 is a miniature, flattened-globose selection of white for with uniform, layered branching and blue foliage. After 10 years of growth, a mature specimen will measure 8 inches (20 cm) tall and 12 inches (30 cm) wide, an annual growth rate of 1 inch (2.5 cm) or less. This is a great selection for rockeries, troughs or small home gardens.

This cultivar originated as a witch's broom selected in the early 1990s by Jerry Morris of Lakewood, Colorado. In his field notes, Jerry described the broom as, "a broom, 3 feet wide by 8 feet tall, 12 feet up, pancake, blue. At the start of La Junta Canyon on route 50 in southern Colorado. Mother tree had budworm injuries in 1990." Jerry provisionally named his find Abies concolor [ #5 ], recognizing it as the 5th white fir broom he collected over his long history.
