Award of Garden Merit
Shrubs Conifers

A dwarf, very slow-growing, evergreen coniferous tree reaching only 1m (39in) high and 60cm (2ft) across after about ten years. The tree has an upright, spreading habit with upwardly growing short stems, the tips of which bear short, silvery blue-green needles. These are stiff and produced in groups of fives. They are approximately 3cm (1¼in) long and slightly curved or twisted, giving the tree's canopy a ruffled texture. It is an ideal choice for a small city, or courtyard garden, where an architectural or evergreen focal point is needed
