Which term describes the property of a plant that indicates its suitability for low-maintenance gardening?

The term that best describes the property of a plant that indicates its suitability for low-maintenance gardening is "Ground Cover." Ground cover plants are typically low-growing, spread quickly, and can fill in bare spots in gardens or landscapes, reducing the need for weeding and maintenance. They can suppress weeds, control erosion, and often require less water and fertilizer than traditional lawns, making them ideal for gardeners seeking to minimize upkeep.

In contrast, invasive species are plants that can grow aggressively and displace native vegetation, often creating more maintenance challenges rather than reducing them. Perennials, while they return year after year and might be low-maintenance compared to annuals, still require some upkeep during their life cycle, such as deadheading or division. Annuals complete their life cycle within a single growing season and typically require replanting each year, which increases maintenance demands. Thus, ground covers are specifically designed to minimize maintenance while providing coverage and aesthetic value to the garden.
