Description
Ornemental ivy – Hedera helix ‘Williamsiana’
In a nutshell
Ornamental ivy, Hedera helix ‘Williamsiana’, is particularly interesting for its wavy, hemmed foliage (between ‘Curvaceus’ and ‘Clotted Cream’). Best used as ground cover, like its parent. It is also interesting in large pots and as a climber.
Slow-growing ivy with few branches and stiff, more or less thick stems.
Leaves have 3 to 5 pointed, curved lobes. The base is cordate. The leaf blade is green to gray-green with white margins, turning pink in winter.
It will brighten up a corner of the garden.
History
This cultivar is a mutation of ‘Glacier’, discovered by Keith E. Williams, USA, around 1950.
