| Positive | On Jun 20, 2015, coriaceous from ROSLINDALE, MA wrote: Easy, beautiful. Does well under ordinary garden conditions in full sun---it enjoys boggy conditions but does not require them. It does not require consistent moisture, and is reasonably tolerant of drought. It self-sows here with abandon in ordinary garden soil with no irrigation. |
| Positive | On Jun 20, 2015, Pippinincarnate from Hamburg, NY wrote: I've seen this plant growing wild at the waters edge of presque isle bay in Erie Pennsylvania. HUGE pink blooms in august and september. Apparently it is an adventive species in the northern USA and is now expanding into southern Canada. |
| Neutral | On Jun 28, 2004, Wingnut from Spicewood, TX (Zone 8b) wrote: I haven't grown this plant myself, but have seen it at the Lady Bird Johnson National Wildflower Research Center growing in a bog area and hanging over the pond at the front entrance of the center. It can DEFINITELY live in boggy, wet areas, hence the name "Swamp Rose". |
