The occasional question ...

What is 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 self-branching ivy. The most typical of these is ‘Pittsburgh’ ivy (Hedera helix ‘Pittsburgh’).
