The
Blackthorn tree also know as the Sloe bush (Prunus spinosa) currently
is not common in gardens. I'd like to tell you about it.
Blackthorn
is a deciduous tree, its leaves turn yellow in autumn and fall off in
winter. In nature Blackthorn dwells on the edge of woodlands forming
dense thickets and hedgerows. The Blackthorn ‘tree’ is actually
more like a large shrub, it is absolutely undemanding and can
grow in any soil and not demanding to watering. But drought
practically does not happen here in Northern Europe area, rather
there are days with prolonged rains.
The
tree bears small, delicate, white flowers with oval petals clustered
into a star shape in early spring. They are usually white, but
occasionally pink, with red tipped stamens. The fruit is generally
good for picking after the first frost, when
blue-black sometimes deep purplish fruit is ripe and its bitterness
reduces, the small
plum-like fruit is also known as 'drupes'.
Some
years ago, when I almost planted all my new plants my neighbor
brought a small twig with three roots. It was Blackthorn, she had dug
it of the shrub in her garden. I planted the Sloe
bush near the garden gate.
The
first and second year my Blackthorn only grew, did not bloom, the
third year small white flowers appeared on its branches and in the
autumn it produced one fruit (!). After a year three fruit were and I
told the neighbor that sloe berry harvest has tripled :)).
Last
year black ground ants attacked my young Blackthorn. You're most
likely to see these ants in your garden. They generally nest
underground, sometimes in large colonies, invading homes and gardens
seeking food. These ants are not dangerous to humans, but can be a
nuisance in the garden when they protect aphids.
They
began to grow up aphids on young branches and leaves and my
Blackthorn was suffering. What could I do? I sprayed different means, but the ants still were growing up aphids,
white flowers appeared, began to fade and to wither because aphids
ate all that would grow on the branches. Then I began to search the
internet for advice and the people told how they struggle with
aphids. Gardeners apply a 3-inch wide band of masking tape to a tree,
especially where ants are frequent visitors. Also people told to
place sugar-based ant baits on either side of the ants' trails and
around their nest's opening. I wanted ants out of my garden so I implemented
all recommendations.
At
the fall I picked the fruit after the first frost and decided to use
them at home in winter. I've read that Sloe gin or vodka is a
wonderful Christmas drink, like this one Spanish 'Zoco'.
Even if you don't like gin, it is worth making as it tastes more like a liqueur, as you can make it as sweet as you like.
Sloes
also make a lovely tart jelly to go with game or with your Christmas
dinner as an alternative to cranberry like this 'Sloe jam'.
I've made
jam for pudding, but fruit do need sugar due to their bitterness.
Would
you like to taste Sloe berry wine or jam? Have
you seen this tree or do you have it in your garden?
