Spring in Portland is one of the most rewarding times to get your garden going. With mild temperatures, steady rainfall, and rich soil, the Willamette Valley offers ideal conditions for a wide variety of flowers—from colorful annuals to hardy native perennials.

If you’re wondering what to plant this season, here’s a breakdown of the best spring flowers for Portland gardens, plus tips to help them thrive.

Understanding Portland’s Spring Planting Season

In western Oregon, you can start planting cool-season flowers as early as late March or early April, even before the last frost.

These include hardy varieties that tolerate cooler temperatures and moist soil—perfect for Portland’s early spring weather. Warm-season flowers, however, should be planted later (typically May) once the risk of frost has passed.
