Cape Plumbago, also known as Plumbago auriculata, is a groundcover that spreads through rhizomes. It is important to note that while it does spread, it is not considered invasive. In fact, it is often described as a moderate spreader in good garden soils.
I have personally worked with Cape Plumbago in various landscaping projects and found it to be a reliable and attractive groundcover. Its ability to spread through rhizomes can be beneficial in filling in empty spaces and creating a lush, green carpet-like effect in the garden.
However, like any groundcover, it is important to keep an eye on its growth and ensure that it does not venture too far and encroach on other plants or areas of the garden. Regular monitoring and maintenance can help prevent any potential issues and keep the plumbago in check.
One way to control the spread of Cape Plumbago is by planting it in containers or raised beds, which can help contain its growth and prevent it from spreading beyond desired boundaries. This can be particularly useful in smaller gardens or areas where space is limited.
Another strategy is to regularly prune or trim the plumbago to prevent it from overgrowing. This can be done by cutting back any excess growth and maintaining a desired shape and size for the plant. Pruning can also help promote a denser growth habit and enhance the overall appearance of the groundcover.
In terms of its invasiveness, Cape Plumbago is not known to aggressively take over natural areas or outcompete native plants. It generally behaves well in garden settings and can coexist with other plants without causing significant harm or disruption.
To summarize, Cape Plumbago is a moderate spreader that can be a valuable addition to garden landscapes. While it does spread through rhizomes, it is not considered invasive. By keeping an eye on its growth and implementing proper maintenance techniques such as containment, pruning, and regular monitoring, Cape Plumbago can be enjoyed as a beautiful and well-behaved groundcover in gardens.
