A.R.Wallace Quote

“The beauty and brilliancy of this insect are indescribable, and none but a naturalist can understand the intense excitement I experienced when I at length captured it. On taking it out of my net and opening the glorious wings, my heart began to beat violently, the blood rushed to my head, and I felt much more like fainting than I have done when in apprehension of immediate death. I had a headache the rest of the day, so great was the excitement produced by what will appear to most people a very inadequate cause.” A.R.Wallace

Ivy (Hedera helix)

Ivy is such a good late source of food for many insects and is a habitat in itself, the shelter it provides in its twisting vine like stems.

About this species

Common ivy is a popular ornamental, valued for its ability to thrive in shady places, provide excellent groundcover and cover unsightly walls, sheds and tree stumps. Many cultivars are available, including variegated forms that can be used to brighten shady depths of winter gardens.

Long collected for winter decorations, common ivy is associated with Christmas and frequently features in festive designs. It is also an important source of food and shelter for wildlife during winter.

Ivy is not a parasite, does not normally damage sound buildings or walls, and is rarely a threat to healthy trees. Regular trimming can prevent ivy becoming too heavy, a problem that can be exacerbated by the additional weight of rain and snow.
