Picea engelmannii 'Bush's Lace' / Bush's Lace Engelmann Spruce

Picea engelmannii 'Bush's Lace' is a vigorous, large, upright-growing selection of Engelmann spruce with very attractive powder-Blue needles and semi-pendulous branching the creates a cloaked effect and a skirt at the base of the plant. It's striking color and form looks particularly great against a dark background. As stated this plant in known for exceptional vigor. When cultivated under good conditions, it will grow in excess of 2 feet (60 cm) per year and can be reasonably expected to reach heights of 12 feet (4 m) or more after 10 years in the landscape. It is known to be very cold hardy, but may struggle in hot climates above zone 6, especially those with warm, humid nights. Like other P. engelmannii, there is ample anecdotal evidence of it doing fine in Mediterranean zones 8-9 on the West Coast of the U.S.

This cultivar originated as a specimen selected by Dick Bush of Aurora, Oregon on a local Christmas tree farm.

Is this plant resistant or at least less susceptible to Cytospora canker and Rhizospaera needle blight? My neighbor insisted on planting a blue spruce and surprise, it is loaded with both the above diseases. I really like 'Bush's Lace' and want to know if anyone has seen the same diseases on Engelmann spruce or this cultivar. I would hate to get a plant and it look terrible in a couple of years due to diseases. Thanks, Laura Jull

Don't know where you live, but spruces outside their natural range (and elevation) are more susceptible to canker. Canker is dispersed through spores so if your neighbor has it — chances are it could migrate over. Maybe look for columnar pine trees instead?
