Definition

Noun: 1. A large taxonomic category of plants: "genus Rhododendron" is the scientific name for a large group of closely related evergreen shrubs. This genus is characterized by plants native to cooler regions of the Northern Hemisphere, many of which are cultivated for their showy, often colorful flowers.

Usage

• "Genus " is used in scientific, botanical, and horticultural contexts to refer to the entire group of plants sharing these characteristics.
• It is a formal, taxonomic term. In everyday gardening language, people typically just say "rhododendron."

Examples

• Botanists study the diversity of flower shapes across the genus Rhododendron.
• Many species in genus Rhododendron require acidic soil to thrive.

Advanced Usage
