Ecology
| Wildlife: |
| |
| Insects: | Mostly pollinated by sap beetles. The beetles are drawn by the scent of fermentation, and they work their way into the shade of the overlapping tepals to find food. The flowers are easy to enter but difficult to depart. Once trapped inside, the beetle picks up pollen. After the flower is pollinated, the inner parts of the flower fold back to release the beetle. By that point, the stigmas will have withered, and the beetle will move on to another flower in search of more food, ensuring cross-pollination (Arnold Arboretum) | |
| Native Habitats: | Mesic-wet mesic sites. Slope forests, bluffs, riverine floodplain, upland hardwood forest, slope forest, bottomland forest. Found on stream banks. |
