1. The plural of perennation; the process or strategy by which a plant survives unfavorable seasons (such as winter or drought) and lives for more than two years.
Usage: botanical term; typically used in ecology and plant biology
2. The structures or organs (such as bulbs, rhizomes, or tubers) that enable plants to persist through dormant periods.
Usage: botanical term; often refers to the physical mechanisms of survival

Examples

• Many temperate plants rely on perennations such as underground bulbs to survive harsh winters.
• The study examined different perennations used by desert plants to endure prolonged droughts.
• Rhizomes and tubers are common perennations that allow plants to regenerate each growing season.
• Perennations enable perennial plants to persist in their habitats year after year.
• Botanists classify plant survival mechanisms into several types of perennations based on their structure and function.
