Colorado Blue Spruce ‘Moonstone’ (Picea pungens ‘Moonstone’). Picea abies ‘Moonstone’ is a dense, conical variety, distinguished by its almost pearly pale blue young shoots, reminiscent of moon reflections on its mature silvery-blue foliage. Its moderate growth and naturally balanced shape make it an excellent option for contrasting beds or cool garden scenes. ‘Moonstone’ shines with its soft glow and fine texture. The indicated adult size is 1.2 to 1.5 m (4 to 5 feet) in height and 1.2 m (4 feet) in width.

To plant Colorado Blue Spruce ‘Moonstone’, choose a suitable exposure: full sun. The recommended soil is: acidic to slightly acidic, well-drained. Respect the conifer's natural silhouette and avoid deep pruning into parts without foliage. Monitor moisture after planting, including in the fall when the weather is dry. Aeration and drainage are as important as watering frequency. Water the root ball before planting and ensure that water can drain after planting. During establishment, check the moisture by hand before watering again.

Allow a width of 1.2 m (4 feet) to plan this plant's space in the garden. The indicated height of 1.2 to 1.5 m (4 to 5 feet) helps to choose its position relative to neighboring plants. Keep access to the base to weed, check moisture, and remove damaged parts. Associate this variety with plants whose light and water needs are compatible. If you are considering a container, first check that its volume and drainage are suitable for root development. Potted roots are more exposed to cold than those planted in the ground.
