For optimal landscape design, what is crucial to consider regarding plant species?

Considering the hardiness and suitability of plant species for the environment is vital for optimal landscape design because it ensures that the plants will thrive in the specific conditions of a given location. This includes factors such as climate, soil type, moisture levels, and exposure to sunlight. Selecting plants that are well-suited to these environmental conditions promotes healthy growth, reduces maintenance needs, and enhances the longevity of the landscape.

When plants are chosen based on their hardiness, it minimizes the risk of failure due to unsuitable growing conditions that could lead to stress, disease, or death. Furthermore, a well-planned selection contributes to a sustainable landscape that requires less intervention and resources to maintain.

While factors like flowering season, autumn color, and maximum height are relevant for aesthetics and design aspects, they do not directly impact the fundamental viability of the plants in their environment. Prioritizing hardiness and suitability ensures that all other considerations can be effectively met over time.
