Picea glauca 'Haal' / Haal Alberta spruce

Picea glauca var. albertiana 'Haal' is one of the many Blue-needled selections of Alberta spruce. Growth habit and structure is similar to the typical cultivariant, with 'Haal' being perhaps a bit narrower and growths at half the rate of 'Conica.' After 10 years of growth, a mature specimen will be around 3 feet (1 m) tall and 1.5 feet (0.5 m) wide. It should be noted that very few of these Blue-needled forms are stable and will develop green reversions over time. If these are not removed, the plant will gradually become variegated and eventually mostly green in color.

This cultivar originated as a Blue sport on a specimen of 'Conica' found by Isaac and Richard Bos at their nursery in Surrey, UK in the mid 1990s. They applied and were awarded patent number USPP11473 for this introduction in 2000.
