Plant hardiness refers to the ability of a plant to survive adverse environmental conditions, and it can vary significantly based on climate conditions. When evaluating different climates, factors such as temperature extremes, moisture availability, and exposure to wind or frost play crucial roles in determining a plant's resilience.

For instance, a plant species might be well-suited to a specific range of temperatures but could struggle in excessively cold or hot conditions outside of that range. Additionally, changes in moisture levels can influence a plant's hardiness; plants may become more susceptible to diseases and pests if they are stressed due to drought or excessive rainfall.

Variations in climate can thus directly affect a plant's life cycle, growth rate, and overall health, highlighting that hardiness is not a fixed trait but one that can fluctuate in response to environmental stressors. This understanding is essential for gardeners and landscapers in choosing appropriate plants for their regions, ensuring that the plants selected will thrive under local climate conditions.
