The European Cornel (Cornus mas) is a species of dogwood native
to southern Europe and southwest Asia. In North America, the plant
is known by the common name of Cornelian Cherry.

It is a medium to large deciduous shrub or small tree growing to
5-12 m tall, with dark brown branches and greenish twigs. The
leaves are opposite, 4-10 cm long and 2-4 cm broad, with an ovate
to oblong shape and an entire margin. The flowers are small
(5-10 mm diameter), with four yellow petals, produced in clusters of
10-25 together in the late winter, well before the leaves appear.
The fruit is an oblong red drupe 2 cm long and 1.5 cm in diameter,
containing a single seed.
