Picea glauca 'Pendula' (Weeping White Spruce)


Michael's Opinion

Weeping White Spruce is suited to the designed landscape since its narrow, dense compact shape and light blue colour present a very architectural but compact, contemporary form.

Description and Growing Information

General DescriptionOften variable in form, being either a narrow tree or a mounding shrub it is quite confusing in stature. Trained as a tree is worth the effort since it presents, a slightly weeping but full, rich, pale blue form.
ShapeOften tall, it has a narrow, weeping or drooping form which begins to bend at the terminal as the tree matures. Otherwise when grown as a shrub it is loosely mounding to sprawling.
LandscapeOften used as a strong central point of focus in a garden if trained as a tree, however if left untended it can also become an informal accent or specimen plant.
PropagationGraft onto 2 year old Picea glauca rootstock in November, keeping the graft union moist, ideally packed in peat moss under bottom heat with intermittent mist.
CultivationWeeping White Spruce is suited to full sun and is able to adapt to dry or moist conditions, however it is intolerant on saturated soils. It is a drought, pollution and road salt tolerant and is adaptable to most soil pH's with the exception of extremes.
