Silvery foliage, fast growth, a florist's favourite

Description
Eucalyptus 'Baby Blue' is a fast-growing, evergreen tree or large shrub valued for its small, rounded, intensely silver-blue juvenile foliage, which it retains for considerably longer than many eucalyptus species, making it especially useful for foliage and cut-flower work. Aromatic when crushed, the foliage provides year-round structure and colour, and the plant has a naturally bushy, well-branched habit when grown as a shrub or pruned regularly, though it will develop into a substantial tree if left unchecked. It is widely grown both as a striking specimen plant and, when cut back hard annually, as a more compact foliage shrub for borders and large containers, and its silvery leaves are a popular choice for flower arranging. -

Planting guide
Choose a sheltered, sunny position with well-drained soil; Eucalyptus 'Baby Blue' does not tolerate waterlogged conditions, particularly while young. Plant in late spring, once the risk of frost has passed, to give the plant the maximum possible time to establish a strong root system before its first winter; this is more important for eucalyptus than for many other shrubs and trees, as poorly established plants are considerably more vulnerable to winter losses. Stake young plants loosely for the first year or two if grown in an exposed position, as the fast top growth can make them susceptible to wind rock before the roots are well anchored. Water in thoroughly and keep consistently moist through the first one to two growing seasons. If you intend to grow this as a compact, hard-pruned shrub for cutting, decide on this approach early, as the pruning regime should begin once the plant is well established rather than being introduced to an already mature specimen.
Care tips
If growing 'Baby Blue' as a specimen tree, little pruning is required beyond removing any dead, damaged, or crossing growth. If growing as a compact, bushy shrub for the best display of juvenile foliage and a manageable size, cut all the previous season's growth back hard each spring, to within 15–30 cm of the base, once new growth is just beginning to show; this hard annual pruning is what keeps the plant compact and ensures a continuous supply of the prized small, rounded juvenile leaves rather than the longer, more sickle-shaped mature foliage that develops on unpruned growth. Water young plants regularly through their first two growing seasons; established plants are drought-tolerant and need little supplementary watering. No routine feeding is necessary on reasonable soils. For cut foliage, harvest stems at any point through the growing season; the foliage is long-lasting in a vase, fresh or dried.
Winter care
Eucalyptus 'Baby Blue' is fully hardy in most parts of the UK once established, though young plants in their first one to two winters benefit from some protection in colder or more exposed gardens. A dry mulch around the base in autumn helps protect the roots through the first winter or two. No pruning is necessary for winter protection, as eucalyptus are evergreen and do not require the same autumn tidying as deciduous plants. If grown as a hard-pruned coppiced shrub, the main pruning is carried out in spring rather than autumn, so the plant retains its foliage through winter for interest before being cut back as new growth begins.
