Madagascar periwinkle, also known as Catharanthus roseus, is a lovely plant that can add beauty to any garden or landscape. One important thing to keep in mind when considering this plant is its spreading nature. Madagascar periwinkle does spread, and it can cover a significant area in your garden if not properly maintained.
The spreading habit of Madagascar periwinkle is due to its ability to produce lateral shoots or runners. These runners can extend horizontally from the main plant and give rise to new plants. This growth habit allows the plant to spread and fill in empty spaces in your garden.
On average, Madagascar periwinkle can spread about 10-20 inches both in width and height. This means that if you have a small area or limited space, you need to be cautious when planting this species. It can quickly take over neighboring plants or invade areas where you don’t want it to grow.
To control the spreading of Madagascar periwinkle, regular maintenance is necessary. Pruning and trimming the plant can help keep it in check and prevent it from spreading uncontrollably. You can trim back the lateral shoots or runners to restrict their growth and maintain the desired size and shape of the plant.
Another important aspect to consider when growing Madagascar periwinkle is its water requirements. While this plant is known for its tolerance to drought conditions, it still requires moderate watering. It is essential to provide enough water to keep the plant healthy and thriving. However, overwatering should be avoided, as it can promote excessive growth and spread.
In my personal experience, I have seen Madagascar periwinkle spread rapidly in a garden where it was not adequately managed. It started as a small plant in a corner and gradually expanded, covering a considerable area. It took some effort to trim back the runners and keep the plant under control. However, with regular maintenance and pruning, it can be a beautiful addition to any garden without overrunning the space.
To summarize, Madagascar periwinkle is a spreading plant that can cover 10-20 inches in both width and height. Regular pruning and trimming are necessary to control its growth and prevent it from taking over neighboring plants. While it is drought-tolerant, moderate watering is still required. By properly maintaining and managing this plant, you can enjoy its beauty without allowing it to spread excessively.
