Spruce | Picea

The pine family (Pinanceae) consists of a large number of species that can be found everywhere in the temperate regions of the northern hemisphere. Only slow-growing varieties that need no pruning should be grown in containers. Picea pungens ‘Glauca Globosa’ (a form of Colorado spruce) has silvery blue needles and grows 100 cm (39 in) high. P. oriental is (Oriental spruce) has a particularly dense needle-like foliage and is therefore an excellent visual screen. P. abies ‘Acroncona’ has an extraordinarily large number of cones, while the dwarf form ‘Pumila Glauca’ forms cushion-like mounds. It combines beautifully with shrubs and grasses as does the spherical P. omorika ‘Nana’, a dwarf form.

They all prefer a sunny position with sandy, slightly acid soil, rich in humus. They will tolerate periods of drought if planted in a flowerbed but in a container they need regular watering and should be given conifer fertilizer every four weeks.

Picea species can be raised from seed in spring or propagated from semi-ripe cuttings in summer. In winter the roots should be well protected against frost.
