Juniperus virginiana 'Glauca' / Silver Eastern Red-cedar
Juniperus virginiana 'Glauca' is a old cultivar of Eastern Red-cedar which will grow to a mature height of about 25 feet (7.5m) tall in a columnar or narrow pyramidal form, spreading 6 to 8 (2 - 2.5 m) feet wide when given a sunny location. Foliage emerges silver-Blue but fades slightly to Blue-green and the summer progresses. It develops a brownish tint in winter in northern climates. The fruit is a Blue berry on female trees and is ornamental when produced in quantity. Birds devour the fruit and 'plant' it along farm fences and in old abandoned fields.
Élie-Abel Carrière (1818-1896), a leading authority on conifers during the period 1850-1870, published that this cultivar had been in cultivation in France since before 1868.
