Ivy is
a woody, native, evergreen
which may climb up to 30 m in woodland by means of short
roots along the stem which grip any rough surface -
walls or tree bark.
The
flowers are arranged in umbrella-like clusters of many
5-petalled yellowish-green flowers which do not open
until September.
The
fruits, green at first, persist through the winter
turning blue-black when ripe in the late spring or early
summer.
Facts
-
Ivy
is not a parasite: the roots on the stem do not
penetrate the living tissues of the tree it climbs.
-
It
is one of the main food plants of the holly blue
butterfly: the caterpillars eat flower buds, flowers
and young fruits.
-
The
open flowers provide autumn nectar for many insects,
especially flies, whilst the fruits are adored by
birds, particularly blackbirds and thrushes.
