Description
Ornamental ivy - Hedera helix ‘Ria’
In a nutshell
Ornamental ivy, Hedera helix ‘Ria’, is a stocky, slow-growing variety.
The plant has few branches, and the stems with spaced internodes bear very colourful 3-lobed leaves. The 2 x 3 cm leaves are green with a yellow margin and form small but not too thick mats. The edges of the leaf blades, which vary in width, turn golden yellow in summer and remain coloured on mature leaves.
A good ground cover for small areas, it is also interesting in pots.
History
This cultivar is a mutation of ‘Ira’, selected by the Fibrex nursery in the United Kingdom in 2000.

The occasional question ...
What is an internode?
Ivy leaves are arranged alternately on the stem, once on one side and once on the other, and so on. The place where the leaf attaches to the stem is called the node. The space between two consecutive nodes is called the’knot.
The distance between the nodes varies greatly depending on the species and cultivar. The distance between nodes is therefore often a distinctive characteristic of varieties.
Ivy with short internodes is compact and well covered with leaves. They often form thick mats. In contrast, ivy with long internodes has sparser leaves on much longer stems. This type of ivy forms a less dense cover, which can be an advantage or a disadvantage depending on the purpose and the use to which it is to be put.
