The phrase refers to a selection of flora optimally suited to thrive in a specific geographic region characterized by particular climatic conditions. This region, designated as 8a within the USDA Plant Hardiness Zone Map, experiences average minimum winter temperatures ranging from 10F to 15F. Selecting varieties adapted to these temperatures ensures greater success in cultivation and minimizes the risk of winter damage or death.
Proper plant selection according to hardiness zones offers substantial advantages. It contributes to robust growth, prolific flowering and fruiting, and reduces the need for extensive winter protection measures. Historically, understanding regional suitability has been crucial for agricultural success and continues to be a primary consideration in modern horticulture and landscape design. Choosing appropriately helps foster sustainable gardens and landscapes that require less intervention.
