Traveller's
Joy or Old Man's Beard
Clematis vitalba (Ranunculaceae)
On russet
floors, by waters idle,
The pine
lets falls its cone;
The cuckoo
shouts all day at nothing
In leafy
dells alone;
And
traveller’s joy beguiles in autumn
Hears that
have lost their own.
From The
Last Poems
A.E.
Houseman
This
sweet-scented, woody climber is a vigorous perennial which in the
wild can develop twisted, jungle-like, trailing stems as thick as a
man’s wrist. Covered with stringy bark, these grow up to 30 m in
length and from late April carry compound leaves of three to five
pairs of well-spaced, oval, pointed leaflets, each 3-10 cm long,
with lobed margins. When the stalks of the leaflets feel the
pressure of a neighbouring plant they twine round it, using it as a
climbing aid. In July and August fragrant clusters of
greenish-white, four-sepalled flowers each 2 cm wide and with masses
of stamens round the central group of long, hairy styles. These
become the glorious, whitish, fluffy fruiting heads which often last
until late winter and give the vine its other common name, old
man’s beard. The long, feathery plume on each seed helps wind
dispersal.
Traveller’s
joy is found in hedgerows, woodland and scrub, usually on alkaline
soils with a pH above 6.0, in the lowlands south of a line joining
the Humber and Dee estuaries.
This climber
can be grown through hedges, along fences or as a covering for a
dead tree. But take care that it does not smother young plants or
get a grip in open ground were it will quickly take over. It grows
in sun or semi-shade and prefers alkaline soil. It is easily
propagated by taking inter-nodal cuttings in summer or from ripe
seed sown in late autumn and potted out in spring. They can be
planted out the following autumn or spring.
The
pollen-rich flowers are visited by numerous insects, including
hoverflies and bees, both for pollen and the nectar at the base of
the filaments. The leaves are food for the caterpillars of species
of tortricoid moths. The whole plant provides cover for nesting
birds and food for insectivores such as birds, shrews, bats, and
other small mammals and frogs.
