Description
Irish ivy - Hedera hibernica ‘Dealbata’
In a nutshell
Irish ivy, Hedera hibernica ‘Dealbata’, It has small, triangular, variegated leaves.
The leaf blade is dark green, splashed with white or cream on new leaves. The variegation often appears at the tip of a lobe, fading towards the centre of the leaf. It is more pronounced if the ivy grows in poor soil and in the sun. The creamy white area turns pink in dry, cold weather. Mature leaves turn entirely green. The stems are pink-red. The internodes are fairly long. The plant is well branched.
This is an interesting ivy in a pot because of its long, drooping stems.
History
This ivy was discovered in the wild in the east of the Snowdonian massif, Wales, United Kingdom. It was described by Hibbert in 1872. It has long been considered to be part of the species Hedera helix, instead of Hedera hibernica. However, as early as 1912, Tobler considered it to be a hibernica. This classification has recently been confirmed by chromosome counting. In addition, a cultivar known as ‘Howardii’, or ‘Howardiana’, distributed from the 1920s onwards, turned out to be ‘Dealbata’.

All about the health of my ivy
Ivy anthracnose
Ivy is virtually disease-free, especially when grown outdoors on vertical supports. Indoors, or as ground cover in damp conditions, diseases such as ivy anthracnose can sometimes occur.
Causes :
This disease is caused by a fungus (Colletotrichum trichellum), which develops in overly humid growing conditions. It appears particularly in autumn on young shoots.
Symptoms :
Symptoms appear as brown spots 1 cm in diameter. These gradually enlarge and the entire leaf is destroyed.
Treatment :
As a preventive measure, avoid getting leaves wet. Prune and remove infected areas, improve air circulation around plants, and apply specific fungicides if necessary.
