Hedera helix

Hedera helix
Common Ivy, English Ivy
Lierre


Native to most of Europe and western Asia
Juvenile stage is the climbing/spreading stage in which plants produce thick, 5-lobed leaves on non-flowering stems. Adult stage is the shrubby non-climbing stage with unlobed, cordate leaves, and round umbrella-like clusters of greenish white flowers in early fall, followed by blue-black berries.

The flowers are very rich in nectar, an important late autumn food source for bees and other insects. The purple-black berries ripen in late winter, providing an important food source for many birds.
