Celebrate spring and trillium in Tryon Creek this weekend at the Trillium Festival


Join the Friends of Tryon Creek for their annual Trillium Festival on April 1-2 at Tryon Creek State Park. This community event will welcome spring, celebrate the annual return of the trillium, and teach attendees about the benefits of native plants.

Native plants provide wildlife habitat, filter stormwater, and help stabilize slopes. Environmental Services does restoration projects on public land with native plants through the city, including in the Tryon Creek Watershed. Property owners and residents can also get involved by removing non-native invasive species and replacing them with native plants. Natives are well-suited to the amount of rainfall, soils and sun exposure that are typical in Portland, so they tend to thrive.

Please note that Terwilliger Blvd from Hwy 43 up to the Park is closed due to sewer construction. See for more information about the project and associated road closures and detours.
