Description
Ornamental ivy - Hedera helix ‘Knülch’
In a nutshell
Ornamental ivy, Hedera helix ‘Knülch’, is interesting for its atypical foliage. Its leaves are almost round and concave, more or less embossed.
The leaves are light green, turning dark green at maturity. It is self-branching with light purple stems. The internodes are short. The leaves have scurved edges, giving the plant a cupped shape.
It does not like damp conditions, especially in winter. It is a good ground cover for small areas of the garden.
History
This cultivar was discovered by Brother Ingobert Heieck from the monastery in Neuburg, Germany in 1977. It is a mutation of ‘Shamrock’.

The occasional question ...
What is self-branching ivy?
Ivy can form long stems, like lianas, to which leaves are attached in alternate arrangements. For some ivy species, these stems are unbranched, meaning that no secondary branches grow from the vines. In this case, we would say that these ivies are not branched.
Conversely, in other species, numerous secondary branches grow from the main stem, in the leaf axils. These are known as branching ivy.
Ivy can be forced to form secondary branches by regular pruning. Those that form secondary branches without being pruned are known as ivy. self-ramifying (self-ramification or self-branching). The most typical of these is ‘Pittsburgh’ ivy (Hedera helix ‘Pittsburgh’).
Ivy in literature
“Ivy, like a faithful companion, covered everything, even the windows, as if to hide the decrepitude of the years.”
