Description
English ivy – Hedera helix
In a nutshell
Common ivy, Hedera helix, or English ivy, or wood ivy, is an excellent ground cover or an ideal climber, depending on the use you reserve for it or the environment in which it grows.
Leaves form 3 to 7 lobes, with a central lobe that is clearly more developed. The overall shape is triangular to oval. The base is variable, sometimes sagittate, sometimes cordate, rounded or even truncated.
The veins are a pale green, sometimes silvery or whitish.
The leaves of the adult stage are elliptical or oval, without lobes.
History
This species has existed since the end of the Secondary Era, about 100 million years ago. It grew in warm, humid regions alongside tropical plants.
