Description

Ornamental ivy - Hedera helix ‘Cockle Shell’

In a nutshell

Ornamental ivy, Hedera helix ‘Cockle Shell’, is a ground-cover variety with a high decorative value.

The leaves are thick, dark green and shell-shaped. In the youngest leaves, the shell faces upwards. Older leaves may have the shell tilted downwards. The leaf blade is fan-shaped. The lobes, if any, are reduced to small teeth, 3 to 5 in number. The veins are prominent.

This ivy does not like prolonged dampness, which can cause necrosis of the foliage. It is perfect in a bed. With its shrubby habit, it doesn't send out stems that could invade other plants.
