Variegated vinca vine, also known as Vinca major ‘Variegata’, is a popular ground cover plant that can be grown in containers outside of zone 7. It is a versatile plant that adds a touch of greenery and vibrant color to any garden or landscape. However, it is important to note that variegated vinca vine is considered invasive in several states, including Virginia, South Carolina, Georgia, Alabama, and California.
One of the characteristics that contribute to its invasive nature is its ability to spread rapidly. The non-flowering stems of variegated vinca vine grow along the ground, forming a dense mat of foliage. Meanwhile, the flowering stems stand upright, showcasing clusters of delicate purple-blue flowers. As the stems come in contact with the surrounding soil, they have the tendency to root, forming new plants. This means that variegated vinca vine can quickly take over an area if not properly controlled.
I have personally experienced the invasiveness of variegated vinca vine in my own garden. I introduced this plant as a ground cover thinking it would add beauty and fill in bare spots. However, I soon realized that it was spreading aggressively and choking out other plants in its path. It took quite a bit of effort to remove and control its growth.
To prevent variegated vinca vine from becoming invasive, it is essential to implement proper management strategies. Here are some recommendations:
1. Regular monitoring: Keep a close eye on the plant’s growth and spread. Regularly inspect the area where it is planted and promptly remove any runners that are trying to root in unwanted areas.
2. Physical barriers: Install physical barriers such as edging or root barriers to contain the spread of variegated vinca vine. This can help restrict its growth and prevent it from taking over neighboring plants or areas.
3. Hand pulling: If you notice variegated vinca vine starting to invade an area where it is not desired, you can manually pull out the runners and root them out. Be sure to remove as much of the root system as possible to prevent regrowth.
4. Mulching: Applying a layer of mulch around the base of variegated vinca vine can help suppress its growth and reduce the chances of it spreading. Mulch also helps retain moisture in the soil and improves overall plant health.
5. Chemical control: In severe cases of variegated vinca vine invasion, herbicides can be used as a last resort. However, it is important to carefully follow the instructions on the product label and use herbicides responsibly to minimize harm to other plants and the environment.
It is important to note that while variegated vinca vine may be invasive in certain areas, it can still be a valuable addition to a garden if managed properly. Its attractive variegated foliage and delicate flowers can provide a lovely contrast and ground cover. However, it is crucial to be aware of its potential invasiveness and take proactive measures to control its spread.
