Description
Ornemental ivy – Hedera helix ‘Atropurpurea’
In a nutshell
Ornamental ivy, Hedera helix ‘Atropurpurea’, is a plant that doesn’t go unnoticed, especially in winter. In cold weather, it turns bronze-purple to dark purple, a color that contrasts magnificently with the ever-pale-green leaf veins. Its coloring becomes more pronounced in sunny situations.
Leaves have 3 to 5 almost triangular lobes, sometimes with two auricles at the base, and a very elongated terminal lobe.
It’s a fast-growing ivy, equally at home in sun or shade.
History
This variety was recovered from the wild by Thomas Williams who initially named it Hedera purpurascens.

The question of circumstance ...
What is an auricle?
The vocabulary used by botanists to describe plants is very rich. For leaves alone, you may come across dozens of specific terms.
At the base of some leaves, two small lobes resembling the base of an ear can form: these are called auricles, for their resemblance to the shape of an ear. The leaf is said to be auriculate.
