cluster rose
Rosa pisocarpaAlso known as Swamp Rose, Pea Fruit Rose
Cluster rose forms dense, tangled thickets along Pacific Northwest streams and wetland margins, providing vital cover for nesting songbirds and small mammals. Fragrant pink blossoms open in small clusters throughout early summer, giving way to bright egg-shaped hips that persist into winter as foliage turns brilliant yellow and red. Straight paired prickles situated at the stem nodes help anchor branches while deterring larger browsing mammals.

- Why interaction risk is low
- Wild fruits and berries have toxic look-alikes; never eat based on app identification alone.
Responsible observation
- Identification: Look for pairs of straight prickles directly below the stem nodes to separate it from look-alikes.
- Habitat Spotting: Search moist streambanks and marsh borders during early summer for pink floral clusters.
