Travel to Portland in the spring and you’ll see exactly why the town is known as the “City of Roses.” Portland’s climate is ideal for growing roses, which start to bloom in April and peak in June. You can see and smell literally thousands of roses at Portland’s popular International Rose Test Garden, which is one of dozens of unique parks and gardens scattered across the city. Don’t miss the Portland Rose Festival, which runs from mid-May through mid-June and features flower shows, parades, fireworks and more.
