What characteristic is NOT typically considered when selecting plant species for landscaping?

When selecting plant species for landscaping, flower color is often considered more of an aesthetic detail rather than a primary characteristic influencing the overall health and success of the landscaping project. Landscape design typically prioritizes functional factors that contribute to the longevity and suitability of plants in a specific environment, such as space requirements, climate adaptability, and growth rate.

Space requirements help determine how much room a plant will need as it matures, ensuring that it fits well within the overall design without overcrowding or competing for resources. Climate adaptability is crucial because it ensures that the chosen plants can thrive in the local environmental conditions, such as temperature, rainfall, and seasonal changes. Growth rate is also important as it impacts how quickly the landscape will fill in and achieve its intended look, affecting both aesthetic value and maintenance considerations.

While flower color contributes significantly to the visual appeal of a landscape, it is not typically a foundational characteristic used for the environmental and practical selection of plant species. Hence, it stands out as the characteristic that is not as critically considered in the selection process compared to the others mentioned.
