Basket grass (Oplismenus hirtellus) is a versatile perennial grass, often used for its ornamental qualities. Also known as woodland grass or basketgrass, this low-growing, spreading species forms an attractive groundcover. It adapts well to various environments, and its popularity stems from its adaptability and the benefits it offers to a garden space.
Groundcover and Aesthetic Advantages
Oplismenus hirtellus excels as a groundcover, creating a lush, carpet-like effect that enhances visual appeal. Its broad, lance-shaped leaves are typically deep green, with some cultivated varieties displaying variegated foliage in hues of mint green, cream, and pink. This plant is effective in illuminating dark, shaded areas where many other plants struggle. It can fill spaces beneath trees, soften borders, or provide a backdrop for other shade-loving flora.
Beyond its role as a groundcover, basket grass also serves as an appealing trailing plant for containers and hanging baskets. Its stems, typically growing 3 to 6 inches in height, cascade gracefully over the edges, adding texture and movement to potted arrangements. The plant’s ability to root at its nodes contributes to its vigorous spreading habit, allowing it to quickly establish a dense cover. This makes it a suitable choice for creating a cohesive and verdant underplanting.
Low Maintenance and Practical Benefits
Oplismenus hirtellus is recognized for its ease of care and adaptability. Once established, this grass exhibits drought tolerance, reducing the need for frequent watering. While it prefers consistently moist, well-drained soils, it adapts to a range of soil types and pH levels, showcasing its resilience. This adaptability means less intensive soil amendment is typically required during planting.
The dense growth habit of basket grass is highly effective in suppressing weeds. By forming a thick mat over the soil surface, it inhibits weed seed germination and growth, reducing the need for manual weeding. This also contributes to its benefits for erosion control, particularly on slopes. The spreading root system of Oplismenus hirtellus helps stabilize the soil, minimizing runoff and preventing soil displacement.
Ecological Contributions
Beyond its ornamental and practical advantages, Oplismenus hirtellus provides ecological contributions to a garden environment. As a dense groundcover, it offers shelter for small wildlife, including insects and amphibians, creating microhabitats. This provides a protected space for these creatures, contributing to local biodiversity.
The presence of basket grass also supports soil health. Its extensive root system helps retain soil moisture by reducing evaporation from the soil surface. This moisture retention, combined with its ability to mitigate soil runoff, contributes to a stable and healthy soil ecosystem. However, Oplismenus hirtellus can spread vigorously, and in some regions, it has the potential to outcompete native plants, requiring management to prevent ecological disruption.
