Description
Ornemental ivy – Hedera helix ‘Nigra Aurea’
In a nutshell
Ornamental ivy, Hedera helix ‘Nigra Aurea’, is a good climber. It will brighten up a corner of your garden.
The dark green foliage gives rise to young yellow shoots that will gradually become green.
The three-lobed leaf is of medium size (4 x 4 cm). In winter, it darkens considerably until it becomes green-black.
Rather branchy, it forms thin mattresses.

A new look at ivy ...
Ivy is an excellent insulator?
Measurements were taken over several years, and in different seasons, on various public buildings covered with ivy. The results are clear: indoor temperature differences are reduced by 3 to 4 degrees. Ivy protects against both cold and heat.
With global warming and energy shortages, urban architects are well aware of the benefits of plant cover on building walls.
Ivy is one of the easiest plants to use for this purpose: “it’s the perfect plant for insulating facades and keeping them dry”, says CGConcept.
Some cities are beginning to consider planting ivy at the foot of public buildings to reduce energy bills.

Ivy in literature
“The ivy, a symbol of constancy, contrasted with the corruption of Dorian’s soul.”
