Blue Wonder Spruce Tree

Blue Wonder is sold as a Colorado blue spruce and identified by Vans Pines as the Deloras selection. Its blue-toned needles develop as the tree matures and may revert toward green. [Vans Pines](https://vanspinesnursery.com/product/blue-wonder-colorado-spruce/) lists the tree for windbreaks, erosion control, bonsai and Christmas tree production, and notes that siskins, nuthatches and crossbills use it for food and shelter. ## Growing Conditions Vans Pines lists hardiness zones 3–7, full sun to part shade, soil pH 5.5–7.0, adaptable soil, mature height near 100 feet and spread about 25 feet. A separate nursery profile reports different size and hardiness figures, so confirm plant provenance and available space before planting near a limit. [Johnston’s Evergreen Nursery](https://www.johnstonplants.com/products/picea-pungens-glauca-blue-wonder-blue-wonder-colorado-blue-spruce) lists 60 feet and zone 2 for a plant sold under the same common name. ## Maintenance Choose a site with good drainage and avoid standing water. The grower lists drought tolerance and sensitivity to excessive moisture; monitor for needlecast, tip blight, canker, aphids, gall adelgids and spider mites.
