I rooted this plant in water years ago (2003), and planted in a pot. It always suffered, having dried out several times in a 9 inch pot. I imagine that this could easily be invasive. I moved it in a nicer and bigger pot, and it flowered a few times even when I haven't paid any attention it. I wonder why it's not in more gardens.
Precisely because it IS invasive, Enrique. I've grown it and enjoyed it, BUT, and this is an enormous, "BUT", it propagates itself profusely, even when conditions don't seem conducive to it. I raised several seedlings from it including Double Poterifolia.
Which I had to let go due to room and how invasive it was. And, I grow Poterifolia X Old Blush, which I have to keep dried out and starved in a can on pavers to prevent it from helping itself to the surrounding area.
I've heard poterifolia is used as a ground cover around ski chalets where snow cover permits skiing right up to the doors of the buildings, over the rose. I agree it's a lovely, interesting "little" rose, but only if you have the acreage it demands.
The specimen in my local botanic garden formed a 20 foot wide mat, right up to the trunk of an oak tree (and would grow wider if they let it!): it's the only 'true' groundcover rose I've seen, dense enough to keep weeds from growing. It would be interesting to see how it grows in it's native habitat.
I'm sure with some effort, it could produce much better landscape roses than those available on the market, but the thought of all the once-blooming behemoths it is sure to produce is discouraging.
