Blackthorn
also called Sloe (Prunus spinosa)
The fruit of the blackthorn is a
type of plum. The shrub or small tree grows to 12-15 feet and is
native to Eurasia and North Africa. In early spring it blossoms
profusely with small white flowers on leafless branches. In summer
the flowers are followed by 1/2 inch, prune-like fruit that can be used
to make a very tart jam.
Blackthorn
is a deciduous, much branched shrub, up to 4 m high. It is often found
in lowland woodland margins, scrub and hedgerows, on a wide range of
soils. It is only absent from extremely acid soils. The short branches
which are at right angles to the stem lose their leaves and then persist
as thorns.The buds are tiny (<2mm), often in clusters of 3-5 (unlike
Hawthorn). The stem is dark to blackish (unlike Hawthorn). The white
5-petalled flowers open in March and April before the leaves which
follow in late April. The fruits, like small plums, become the
blue-black 'sloes' which are ripe in September and October. The fruits
which are used for sloe gin should not be gathered until the first
frosts have reduced their tannin content.
The low-growing thorny bush is
an excellent protected site for shy nesting birds such as nightingales.
The leaves are the food of the caterpillars of brown and black
hairstreak butterflies. It has had many uses and is an ideal tree to cut
for walking sticks or tough shillelaghs. Its fruits can be used for
making wine or as a flavoring for gin. Sloe gin is made by filling a
bottle with sloes, adding some sugar, topping up with gin and leaving
for as long as possible before drinking. |
