Description
Ornamental ivy - Hedera helix ‘Troll’
In a nutshell
Ornamental ivy, Hedera helix ‘Troll’, is a miniature ivy, resembling ‘Triton’ but smaller, with shorter internodes and shorter leaves. The leaves are slightly twisted and composed of 3 to 5 lobes, with a median lobe that is larger than the lateral lobes. The leaf blade is light to medium green. Many of the closely-spaced veins are lighter and contrast well, giving it a lovely texture.
It is a compact plant with strong, sometimes upright stems.
It makes a very attractive, fast-growing ground cover in any position.
History
This cultivar is a mutation of ‘Pittsburgh’, introduced by Maegaard Nurseries in Ringe, Denmark, in 1989.

The occasional question ...
What is an acuminate leaf?
The vocabulary used by botanists to describe plants is very rich. For leaves alone, you can come across dozens of specific terms.
An ivy leaf is said to be acuminate when it ends in a long, thin point.
Ivy in literature
“The altar, covered in ivy, bore the mark of age-old devotion.”
