Description

Ornamental ivy - Hedera helix ‘Pittsburgh’

In a nutshell

Ornamental ivy, Hedera helix ‘Pittsburgh’, is the father of a large number of branched cultivars.

The leaves have the appearance of typical ivy, with 3 to 5 more or less pointed lobes. But what makes it special is the fact that the internodes are very short and, above all, the stems are stiff and branch easily. All this gives this ivy a shrubby appearance, or more accurately, the appearance of a mound of multiple short stems. The base of the leaves is cordate. The blade is medium green.

It is a very good ground cover plant, forming thick carpets. It grows moderately fast, with shoots no longer than 50 cm a year.

History

This cultivar was discovered by Paul Randolph, Verona, Pennsylvania, USA in the late 1910s.
