Members of the genus Myrtus–commonly called Myrtles–are upright and rounded evergreen shrubs and trees. They are grown for their aromatic leaves and their solitary, bowl-shaped, fragrant white flowers.
Myrtles can be grown in shrub borders, as topiaries, or as small houseplants. Myrtus can be grown as an informal hedge. They generally need long, hot summers to produce flowers.
Myrtus is a genus of two species. Myrtus species are native to the Mediterranean region and South America.
