English Ivy (Hedera helix) Where did it come from? Native to Europe, Western Asia, and Northern Africa. Habitat: You’ll find this plant almost anywhere. It can grow in forests, coastal areas, and upland areas, but is most often found in residential areas where it is often planted on purpose. Description: Ivy is an evergreen vine that can trail along the ground or grow vertically up trees, fences, walls and hillsides. Shiny, green, threelobed leaves grow in dense clusters and produce umbrella-like groups of small yellow-green flowers in the fall, followed by dark purple-black berries in the late winter or early spring. Did you know? When English ivy is allowed to grow up tree trunks it can increase the risk of the tree being blown over in windstorms because of the excess weight as well as “sail effect” that is created in the canopy.

Habitat: This plant is abundantly found in open, sunny, disturbed moist areas such as roadsides, fencerows, and riverbeds. Description: Blackberry bushes form dense thickets that can reach up to 15 feet tall. They have large round leaves in groups of five on thorn-covered stems. Black, edible berries are produced and ripen in midsummer. Flowers are small, white to pinkish with five petals. Did you know?
