Ceratostigma plumbaginoides, commonly known as Hardy Plumbago, is a ground covering perennial that is native to Western China. It is often sought after for its beautiful glossy leaves and stunning dark gentian-blue flowers that bloom in late summer through early fall.
One important aspect to note about Ceratostigma plumbaginoides is that it is considered to be a non-invasive species. This means that it does not have a tendency to aggressively spread and take over other areas of the garden or landscape. This is particularly beneficial for those who are looking for a ground cover that will not require constant maintenance and management to keep it in check.
In my personal experience, I have found Ceratostigma plumbaginoides to be a well-behaved plant in my garden. It forms a dense mat of foliage that effectively suppresses weed growth and provides a beautiful carpet-like appearance. I have not observed any signs of it spreading beyond its intended area, making it a great choice for areas where containment is desired.
However, it is important to note that while Ceratostigma plumbaginoides is not invasive, it can still spread gradually through its rhizomatous roots. This means that over time, it may slowly expand its coverage area, but it is unlikely to become a problem or overwhelm other plants in the garden. This slow and steady growth habit is often preferred by gardeners as it allows for easy management and control.
To further prevent any potential spread, it is recommended to regularly prune and trim back Ceratostigma plumbaginoides to keep it within its desired boundaries. This can be done in early spring before new growth begins or after flowering in the fall. Pruning also promotes a more compact and bushier growth habit, enhancing the overall appearance of the plant.
Ceratostigma plumbaginoides is a non-invasive ground cover that adds beauty and color to the garden without posing a threat to other plants. Its glossy leaves and vibrant blue flowers make it a popular choice among gardeners. With proper care and occasional pruning, it can be easily managed and enjoyed without concerns of invasiveness.
