Japanese ivy,\u00a0Hedera rhombea<\/em>, It forms fine, delicate matt leaves with soft green or silvery veins.<\/p>

The overall shape of the leaf is more like a rhombus, hence its name.\u00a0rhombea<\/em>.<\/p>

They generally have 3 to 5 lobes, often shallow. The base is sometimes cordate (heart-shaped), sometimes truncated, sometimes hastate (arrow-shaped). The central lobe is triangular.<\/p>

It is a creeping or climbing ivy, depending on the opportunity. It is vigorous and can grow up to 10 m long.<\/p>

When fully grown, Japanese ivy forms flowers in the form of cream-coloured umbels. It flowers in autumn. The fruit that follows are berries, black when ripe.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

As its name suggests, Japanese ivy comes from eastern Asia, mainly Japan, Taiwan and Korea.<\/p>

Hedera rhombea<\/em> prefers damp, shady areas such as pine forests or riverbanks.<\/p>

On the island of Taiwan, there are ivy plants whose juvenile leaves have a large triangular central lobe with an acuminate tip and truncated base. Some botanists refer to it as the Hedera formosana.<\/em><\/p>

In the same way, another species of ivy from this region, with fine peduncles and pedicels, has been given the name of Hedera pedunculata.<\/em><\/p>

But in both cases, the distinguishing features are quite subtle and, above all, there is a continuity of these features in the field. As a result, the most common conclusion reached by botanists is that these different variants should be recognised as a single species: Hedera rhombea.<\/em><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Ivy is one of the easiest plants to grow in our gardens. It is not demanding in terms of soil type: chalky soil, neutral soil or acidic soil are all suitable (unlike common ivy). Hedera helix<\/em>). In terms of exposure, it thrives in both shade and sun, although it prefers shade or semi-shade. It is drought-resistant, but will grow best in cool soil. If the soil is good, i.e. sufficiently rich in humus, no fertiliser will be needed.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Ivy can be easily integrated into any garden, small or large. Unlike other perennials or climbers, it has the advantage of staying green and beautiful all year round. Hiding an unsightly wall, forming hedges to protect privacy, covering the ground under trees, including fruit trees, dressing the wall of a facade, lighting up a shady area - almost anything is possible with this type of plant. If you're planning to plant an ivy hedge, you'll need to install a wire mesh to support it. Allow 2 to 3 ivy plants per linear metre.<\/p>

However, there are a few uses for ivy that are less recommended: avoid placing it in the middle of rose bushes, as it will tend to suffocate them. The combination of bulbs and ivy is not a happy one either. But there are so many other possibilities with this type of plant. Of course, Japanese ivy has an indisputable place in a Japanese garden, by a spring or to cover rocks, for example.<\/p>

In all cases, plan to prune every year, for example at the end of winter. The aim is to keep the ivy in the area you have set aside for it. Be aware that ivy is a plant that tolerates severe pruning very well, so if you have neglected maintenance for a year or two, you can correct this with a vigorous pruning. Japanese ivy as ground cover offers another significant advantage: weeds are virtually non-existent, as they are smothered by the ivy.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
