Description
Ornamental ivy - Hedera algeriensis ‘Bowle's Ox Heart’ adult
In a nutshell
Like the juvenile form, the adult form of Hedera algeriensis ‘Bowles's Ox Heart’ takes up a lot of space in the garden once installed.
The leaves are unlobed and very broad, certainly one of the largest adult leaves of any hardy ivy species. The leaf blade is a shiny medium green. The margins are slightly undulating. Fruiting takes place in winter. The fruits are black.
It is a stocky ivy with thick, moderately branched stems.
History
This cultivar is thought to be a hybrid between Hedera algeriensis and Hedera hibernica, from the EA Bowles nursery, Enfield, United Kingdom.

The question of circumstance
What is mature ivy?
As it develops, ivy goes through 3 successive stages.
1 - Initially, it crawls on the ground and forms adventitious roots that enable it to crawl further and further, forming an evergreen carpet. This is the juvenile stage.
2 - When it encounters a support, it starts to climb. Instead of adventitious roots, it forms spikes that enable it to climb higher and higher. This is the semi-adult stage.
3 - when it can see enough light, it enters its third stage, known as the mature stage. It now has horizontal branches, rather like a shrub. In autumn, it flowers in greenish umbels that are much appreciated by pollinating and foraging insects. These flowers give rise to berries that gradually ripen over the winter and are eaten by birds.
Adult ivy is therefore of great interest for biodiversity.
By taking cuttings from the parts of an ivy plant corresponding to the adult stage, we obtain adult ivy of the shrub type.
Ivy in literature
“In the grip of the ivy, the ruins seemed to fade slowly into a dream of nature.”
