Hedera helix Shamrock - Common Ivy

Hedera helix Shamrock is a very decorative variety of common ivy that remains attractive all year round. This variety is hardy and indifferent to soil conditions, like most of its relatives. It has small evergreen trilobed leaves of a beautiful shiny green colour. This dwarf variety does not exceed 1.5m (5ft) in height and is particularly suitable for terraces when planted in pots. As the ultimate climbing plant, this ivy can cling to any support to create a beautiful green decoration without the risk of it becoming invasive. It is an easy-to-grow plant that is valuable for decorating shaded areas of the garden.

Ivies belong to the Araliaceae family, which includes relatives such as ginseng and fatsias. This family has about fifty genera and hundreds of species, and it is quite varied, hosting not only trees and lianas but also shrubs and even some herbaceous plants. The Hedera genus includes about a dozen species, with the most common one in Europe being the common ivy or Hedera helix. This giant of European forests can reach lengths of several metres and climb to the tops of the surrounding trees.

Far from the botanical species, 'Shamrock' is a dwarf variety with much more modest growth. It generally does not exceed 1.5m (5ft) in height and 1m (3ft) in spread. Used as ground cover, this ivy can spread a little more, but never to the point of becoming invasive. Shamrock means clover in English, thus evoking its trilobed leaves. Although the leaflets are more elongated than round like clover, their miniature size (about 3cm (1in) long and wide) and their bright green colour are not so different. This shiny, evergreen foliage is decorative all year round and is the main attraction of this climbing plant. In autumn, the nectar from its inconspicuous green flowers, in the form of globular inflorescences, is an excellent source of food for bees at a time when few plants are in bloom.
The stems attach themselves to supports with powerful climbing roots. This ivy can therefore climb a wall or an arch, or even run along the ground. Very easy to grow, this climber thrives in most soil types, except excessively dry ones, and can tolerate limestone. It appreciates a certain level of soil moisture, but once well established, it is rather tolerant of dry conditions. It prefers partial shade or shade, or even full sun in cool climates, but it dislikes excessive sunlight combined with dry air. Hardy, it can withstand temperatures down to about -20°C (-4°F) and can be cultivated practically anywhere without requiring any particular maintenance. An ideal plant for small gardens and beginners.

Hedera helix 'Shamrock' will fit perfectly into a modern garden with its stylish foliage. Its small size makes it particularly suitable for planting in pots, where it can cascade down or climb on a trellis to decorate a balcony or terrace. When planted in the ground, it can serve as a nice ground cover at the base of a tree without the risk of it becoming invasive. It is valuable for enhancing semi-shaded or shaded areas, where you can combine it with other plants that have similar moisture requirements. Its miniature foliage will contrast with the lush leaves of Hostas, either green or bluish, or variegated with yellow or white. To create a scene that is as surprising as it is original, let this ivy weave its way between the clumps of the astonishing Acanthus mollis Tasmanian Angel, a large-leaved acanthus splashed with white. And for enjoying beautiful varied blooms, go for the perennial Geranium (the "true" Geranium in the botanical sense, not the Pelargonium that decorates our window sills), such as the Geranium maculatum var. album, a beautiful variety with bright white flowers.
