Portland Oregon is famously known as the City of Roses due to its annual Rose Festival and large rose gardens.

The nickname City of Roses was given to Portland Oregon because of its longstanding connection to the growing and enjoying of roses. More than 10,000 different kinds of rose plants can be found in the city's International Rose Test Garden. Portland's association with roses is further highlighted by its yearly Rose Festival, a significant event that features parades, regattas, and floral displays. The city is a major hub for rose horticulture and contributes to its lasting floral identity because of its pleasant environment and copious amounts of rainfall, which are perfect for cultivating these flowers.
