Its short, stiff needles exhibit a silvery-blue to steel-blue hue typical of blue spruces, creating a luminous and decorative effect year-round.

To plant 'St. Mary's Broom' Colorado blue spruce, choose an appropriate exposure: full sun. The recommended soil is as follows: well-drained soil, tolerates poor soil. Respect the conifer's natural silhouette and avoid cutting deeply into parts without foliage. Monitor moisture after planting, including in the autumn when the weather is dry.
