Citrus

Citrus genus comprises about 15 species (and many more hybrids and cultivars) of small trees and shrubs, including fruit bearing lemons, limes, oranges, tangerines, and grapefruit. These plants originate in tropical forest and scrub regions of Asia and can be a challenge as indoor plants because of their need for humidity, air circulation and strong light. If successfully grown, however, citrus plants can produce many fragrant flowers and brightly colored fruit in your home.
