About
Citrus reticulata is a spiny, evergreen tree that reaches up to 3 meters in height, featuring glossy, oval leaves that can grow up to 5 centimeters long. In spring, the tree produces highly fragrant white flowers measuring up to 4 centimeters in diameter, which give way to round, slightly flattened orange fruits. This species thrives in a cool or temperate greenhouse or conservatory, with the recommendation to place it outdoors during the summer months.
