What is the study of plant classification known as?

The study of plant classification is known as taxonomy. Taxonomy is the scientific discipline that involves the identification, naming, and classification of organisms, including plants. It organizes species into a hierarchical structure based on shared characteristics and evolutionary relationships, enabling scientists and horticulturists to communicate effectively about different plant species.

Understanding taxonomy is critical for horticulture, as it helps in recognizing the various plants and their corresponding families, genera, and species. This classification can aid in determining the appropriate care, cultivation techniques, and understanding the ecological roles of different plants.

Botany refers to the broader study of plants as a whole, including their physiology, structure, ecology, and evolution, but does not specifically focus on classification. Phylogeny is related to the evolutionary relationships among species, often illustrated in a phylogenetic tree, rather than direct classification. Ecology studies the interactions of organisms with one another and their environment, which, while important for understanding plant habitats, is not concerned with the formal classification of plants.
