Oriental Bittersweet
Introduction
Oriental Bittersweet (Celastrus orbiculatus) is second only to English ivy as the most common invasive vine in Laurel Park. It is a woody perennial like English ivy, but is deciduous (drops leaves in Fall), so you may not notice this vine until Spring.

Description
The leaves are dark green, waxy, and arranged alternately along the stem. Their shape varies, but they are generally three-lobed with a heart-shaped base. However, mature leaves can also be unlobed and spade-shaped. In its juvenile stage, English ivy grows as a dense ground cover; in its adult stage, it becomes a climbing vine. The thick foliage blocks sunlight, restricting the growth of other plants.
Control & Management
Control of English ivy may be achieved through cultural or chemical methods. Please take a look at the NCSU recommendations. To prevent the spread of English ivy, avoid new plantings and dispose of plant parts using your local waste disposal service.
Birds can spread the seeds of English ivy, so it is important to control or remove the vine before the seeds appear.
