More than 1,000 roses bloom late each spring at Rome's Municipal Rose Garden on the eastern side of the Aventine Hill. The sloping garden is divided into two sections separated by Via di Valle Murcia. The upper area is home to the garden's permanent roses, while the lower section contains roses participating in the annual, international Premio Roma competition. Due to the limited nature of the blooming season, the garden is only open from early May to mid or late June. But visitors can come daily, free of charge, and guided tours are available upon request (call to make an appointment).
