Trees with blue (glaucous) and silver
foliage

Broad-leaved

ALNUS INCANA Leaves grey underneath.

CRATAEGUS ORIENTALIS Leaves grey on both
sides, deeply cut.

EUCALYPTUS The tree has numerous species,
but their hardiness over a long period is doubtful;
E. gunnii is the best known.

POPULUS ALBA The white poplar has white
twigs and undersides of the leaves, the best form for
the garden being the erect-growing pyramidalis. P.
canescens
has grey leaves and makes a large, vigorously
suckering tree.

SALIX ALBA The white willow is a large
tree unsuitable for most gardens but its variety sericea
is
a smaller, round-headed tree with whiter leaves.
SORBUS ARIA The whitebeam and all its cultivars have
a persistent vivid, white underside to the leaves; in
lutescens the upper surface also is creamy-white.

TILIA PETIOLARIS This has silvery undersides
to the large, drooping leaves; in T. tomentosa the
underneath is quite white.

Conifers

glaucous-blue, and in some specimens, almost silvery

(better known as ‘Milford Blue Jacket’), robusta
glauca,
‘Silver Queen’ (the foliage turning green
in late summer) and ‘Triomphe de Boskoop’ (tending towards
blue).

CUPRESSUS ARIZONICA ‘Bonita’ has very
grey-blue foliage; in pyramidalis it is somewhat
bluer.

blue foliage; J. recurva coxii has blue-green
leaves; J. virginiana glauca is silvery-blue.

leaves and glauca moerheimii is an even more
intensely colored form.
