It’ll be interesting to see what they have to say about it. I have wondered how often the wild R.blanda growing around me might have R.rugosa in it.

I wonder if this could be about those “hybrid swarms” I saw in Maine???

Speaking of Rosa Rugosa, may I show off a foundling I noticed the other day? The size of the flowers were startling and it’s the first pink rugosa for me (I used to only have red and white). Also I have seen at least one flower have a few more petals than my normal singles(7 or 8).


Wow! Those are the purest pink R.rugosa flowers I have ever seen. Usually they have a blueish hue to them. That one’s a keeper.
