Perennial crops are defined as plants that live for multiple growing seasons. This means they can grow and produce harvests over several years without the need to be replanted each season. One of the key benefits of perennial crops is their ability to establish deep root systems, which can lead to improved resilience against drought and soil erosion. Additionally, because they do not need to be replanted annually, they can reduce labor and costs associated with planting.

The other choices describe different agricultural systems. For instance, the option suggesting plants that are replanted every season refers to annual crops, which necessitate replanting each year to produce. Annual species cultivated for a single harvest also highlight the characteristics of annuals, which align with a different lifecycle and management strategy. The mention of crops that require constant irrigation addresses a specific agricultural practice and is not a defining trait of perennials, as they can vary significantly in their irrigation requirements depending on the species and environmental conditions.
