The International Rose Test Garden in Portland, Oregon, is a must-visit destination for anyone with a love for these vibrant, fragrant flowers. Nestled in the West Hills of Portland, this garden is home to over 10,000 rose bushes of approximately 650 varieties, making it one of the oldest public rose test gardens in the United States. But when is the best time to visit this enchanting garden? Let’s delve into the seasons and find out.
Before we dive into the best time to visit, it’s important to note that the International Rose Test Garden is open year-round, offering a unique experience in each season. However, the peak season for rose enthusiasts is undeniably summer, when the roses are in full bloom. But there’s more to consider than just the roses themselves. Let’s explore the garden’s offerings throughout the year.

Spring: Awakening of the Garden
Spring in Portland brings the garden back to life after the winter slumber. The International Rose Test Garden starts to show signs of life in late March, with early blooming roses like the ‘Julia Child’ and ‘Mutabilis’ putting on a show. By April and May, the garden is a riot of colors as the majority of roses start to bloom.
Spring is an excellent time to visit if you want to witness the transformation of the garden. Plus, the weather is mild, with temperatures ranging from 50°F to 65°F (10°C to 18°C), making it comfortable for a leisurely stroll. However, keep in mind that some popular varieties may not be in full bloom yet, and the garden can be quite crowded during weekends.
Early Spring Blooms
Some of the first roses to bloom in the garden include the ‘Iceberg’ (a classic white rose), the ‘Mutabilis’ (a unique rose that changes color throughout the season), and the ‘Julia Child’ (a vibrant pink rose). These early bloomers signal the start of the rose season and are a delight to behold.
Visiting in early spring also means you can see the garden’s other attractions, like the Shakespeare Garden and the International Rose Test Garden’s memorial to Portland’s Japanese-American community, without the summer crowds. It’s a great time for photography enthusiasts, as the garden’s greenery provides a stunning backdrop for the early blooms.

Spring Events
The garden hosts several events in the spring, including the Rose Festival CityFair and the Portland Rose Festival Grand Floral Parade. These events celebrate Portland’s ‘City of Roses’ nickname and are a must-see for anyone visiting during this time.
However, these events can draw large crowds, so be prepared for potential congestion. If you prefer a quieter visit, consider planning your trip around these events or visiting on a weekday.
Summer: Peak Rose Season
Summer is the peak season for the International Rose Test Garden, with the majority of roses in full bloom from late May to early October. This is the best time to see the garden in all its glory, with a breathtaking display of colors and fragrances. The weather is warm, with temperatures ranging from 65°F to 85°F (18°C to 29°C), perfect for enjoying the outdoors.

However, summer is also the busiest time to visit the garden. If you’re not a fan of crowds, consider visiting on a weekday or early in the morning. Despite the crowds, summer is an unforgettable time to visit, with the garden’s roses reaching their peak beauty.
Summer Blooms
Summer is when you’ll see the garden’s most famous roses in full bloom, including the ‘Mr. Lincoln’ (a deep red hybrid tea rose), the ‘Double Delight’ (a striking pink and white rose), and the ‘Queen Elizabeth’ (a classic yellow rose). These roses, along with hundreds of others, create a stunning display that’s not to be missed.
Summer is also the best time to see the garden’s unique ‘Rose City’ sign, which is made entirely of roses. This iconic sign is a must-see for any visitor to the garden and is a perfect photo opportunity.
Summer Events
The garden hosts several events in the summer, including the Rose Festival CityFair and the Portland Rose Festival Grand Floral Parade. These events celebrate Portland’s ‘City of Roses’ nickname and are a must-see for anyone visiting during this time.

Additionally, the garden offers free guided tours on weekends during the summer months. These tours are a great way to learn about the garden’s history and the roses themselves. However, they can fill up quickly, so be sure to arrive early.
Fall: A Season of Tranquility
Fall in Portland brings cooler temperatures and a change of scenery to the International Rose Test Garden. While the roses start to fade, the garden’s foliage turns vibrant shades of red, orange, and gold, creating a stunning backdrop for the remaining blooms.
Fall is a quieter time to visit the garden, with fewer tourists and cooler temperatures (ranging from 45°F to 65°F or 7°C to 18°C). It’s an ideal time for those who want to enjoy the garden’s beauty without the summer crowds. Plus, the crisp fall air can make the roses’ fragrance even more pronounced.
Fall Blooms
While the majority of roses have faded by fall, there are still some late-blooming varieties to enjoy. The ‘Jens Munk’ (a vibrant orange rose) and the ‘William Baffin’ (a deep red rose) are two examples of roses that often bloom late into the fall.

Fall is also a great time to see the garden’s rose hips, the fruit of the rose plant. These can add a pop of color to the garden and are a sign that the roses are preparing for winter.
Fall Events
The garden hosts fewer events in the fall, but there are still some notable ones to check out. The Rose Festival CityFair and the Portland Rose Festival Grand Floral Parade may be over, but the garden’s annual Rose Show is a must-see for rose enthusiasts.
This event features a display of award-winning roses from around the region and is a great way to learn about the different varieties and their unique characteristics. The Rose Show typically takes place in late September or early October, so be sure to check the garden’s website for the exact dates.
