Description
Non-thorny bush up to 4-5 m high. Reddish bark with
little white elongated spots; oval-shaped leaves, 3-6 cm long, 2-4 cm wide, alternate, entire,
hairless with pronounced secondary nerves in the back. From the principal vein,
eight to twelve parallel veins are originated towards the edges. When young,
they show a couple of basal apexes, the stipules, equal to half the length of
the leafstalk; this one is as long as the third part of the foliar lamina. The
edges of the young twigs turn into an ash-like color and are slightly downy;
the rest of the plant is hairless. Flowers form small groups where the leaves
meet, always in small number. They are small and have a greenish calyx divided
in five lobes, between which some egg-shaped and even smaller petals are
located. Stamens are also five and are found among the petals. Many flowers
die, so that, in general, in the axil of every leave only one or two fruits are
found. Fruits are round berries about the size of a pea (approximately 8 mm diameter). They are green
at the beginning and turn ivory before turning pink; later they turn into a
deep red and finally into a black shining drupe. They have almost no flesh and
have, normally, two or three compressed small seeds. Buckthorn belongs to the
Rhamnaceae family.
It’s native from Europe, Mediterranean regions
and northeast Asia. It grows in mountainous
regions of north and center Iberian Peninsula,
in humid zones, at the edge of brooks and rivers, woods, etc. It blooms in
April and June and is to be harvested at the moment of blooming, if possible
when it is humid because it is when is flexible, preferably in branches of
three to four years of age.
