Dwarf Mondo Grass, scientifically known as Ophiopogon japonicus ‘Nanus’, is a popular choice for gardens and landscapes due to its ability to form dense colonies over time. One of the key factors that contribute to its widespread growth is the underground stolons, or runners, that it produces. These stolons serve as a means for the plant to spread and establish new plants in the surrounding area.
In terms of growth rate, dwarf mondo grass is known for its slow and steady pace. Unlike some fast-spreading groundcovers, it takes its time to expand and fill in an area. On average, it can take around 2-3 years for the plant to spread to approximately 6 inches. This gradual growth rate allows for a more controlled and manageable expansion, making it easier for landscapers and gardeners to maintain the desired look and size of the planting area.
To cover more ground and create a more expansive display of dwarf mondo grass, landscapers often resort to dividing the plants. This process involves separating the existing clumps into smaller sections and replanting them in different locations. By doing so, they can effectively multiply the number of plants and distribute them across a larger area.
I have personally witnessed the spreading nature of dwarf mondo grass in several landscaping projects. In one particular garden, we initially planted a small cluster of dwarf mondo grass near a pathway. Over time, the stolons began to extend and reach outwards, gradually filling in the surrounding soil. It was a fascinating process to observe as the plants expanded and formed a dense carpet-like cover.
It is worth mentioning that the growth rate of dwarf mondo grass can vary depending on various factors such as soil conditions, sunlight exposure, and climate. Optimal growing conditions, including well-drained soil and partial shade, can contribute to a healthier and more vigorous growth. On the other hand, unfavorable conditions may slow down the spread of the plants.
Dwarf mondo grass is a slow-growing groundcover that spreads through underground stolons. Its growth rate averages around 2-3 years to cover approximately 6 inches. Landscapers often divide the plants to cover more area and create a denser display. However, it is essential to consider the environmental conditions and provide suitable care for the plants to ensure optimal growth and expansion.
