Field Notes
Having been inside all day, the cool ocean breeze lured me outside for a walk. I took notice of what looked like some Beach Rose in a flower bed next to a house on Moody Point. Closer inspection confirmed this. There also appeared to be some Rambler Rose along the fence line as well. What surprised me was the discovery of Japanese Beetles all through the the Beach Rose. None were found in the Rambler Rose on the other side of the area.
Supporting Evidence
Photo of my evidence.
The flowers are pink and large, nearly 8cm. This falls within the typical range of 5 to 10cm. You can also see some of the typical wrinkly leaves in the background.
Photo of my evidence.
Some of the early blooms have passed and already been replaced with the recognizable round, red rose hips. Again, the wrinkly composition of the leaves is clear. You can even see some of the small hairs on the bottom of the leaves.
Photo of my evidence.
In this image one can see the alternate compound-pinnate leaves, with 7 leaflets. You can also see that the individual leaves are oval in shape with a toothed edge. You can see the many small and sharp thorns along the main stem.

Your photos back up your comments very well. And, you've listed several characteristics that, when put together, make it clear that this is beach rose.

Good job!

Hello, a weatherhead,

Great to see your recent postings from Southern Maine! And this is a very thorough observation of Rosa rugosa - your images and notes are great.

May I presume that you know the owners of this home? I caution you about posting observations on private property. The presence of some invasive species, though certainly not R. rugosa, can have significant impact on property values. For example, lakefront homes on lakes where aquatic invasive plants are established often have lower values than homes on lakes with no invasives. And in the UK, homes on property where Fallopia japonica is present can sometimes not be insured - no company will take the risk (F. japonica can grow through foundations and destabilize structures). So just mind where you do your research!

And thank you, thank you for publishing what you saw.

cheers,
gbh

I do know the people that live there. And they were OK with me doing a little fieldwork.
