Description
Ornamental ivy - Hedera helix ‘Williamsiana’
In a nutshell
Ornamental ivy, Hedera helix ‘Williamsiana’, is particularly interesting for its wavy, hemmed foliage (it lies between ‘Curvaceus’ and ‘Clotted Cream’). It is best used as a ground cover plant like its parent. It is also interesting in large pots and as a climber.
This is a slow-growing ivy with few branches and stiff, more or less thick stems.
The leaves have 3 to 5 pointed, curved lobes. The base is cordate. The leaf blade is green to grey-green with white margins, turning pink in winter.
It will brighten up a corner of the garden.
