Pinus parviflora (Glauca Group) 'Glauca'

An evergreen coniferous tree capable of reaching 10-15m (33-50ft) high and as much across. when mature. The trees have a densely conical profile when young, but as they mature their shape becomes more spreading. The bark is smooth and greyish-black when young but becomes fissured on older trees. The silvery blue-green needles are stiff and produced in groups of five at the tips of new stems. They are approximately 7.5cm (3in) long and somewhat twisted, giving the trees canopy a ruffled texture. The cones are oval and reddish brown, and produced either singly, or in small clusters and can persist on the tree for around six or seven years, so that over the years, the accumulated numbers of cones remaining on older trees can be very noticeable.
