Hedera, which we commonly refer to as English Ivy (pl. Ivies), is a family of around 20 species of evergreen perennial plants. Depending on their surroundings, these woody plants can be both ground creeping or climbing nearby trees, rocks, buildings, and pretty much anything they can lay their stems on. Given a solid base, the ivy has the ability to crawl up and reach heights of more that 30m. On ground level it rarely exceeds ½ feet in height.As gorgeous as this chef-d'œuvre of nature is, it can still cause mischief around your property if left unattended. It’s considered an invasive plant after all, meaning it’ll not knock on your door to ask if it’d be OK to crash in your yard for the night.
