We have this rose growing on the hillside next to our driveway in a pretty inaccessible place. There was one beautiful bloom last year and that was it. The flowers look white from a distance. The main bush has sent out canes that have rooted and sent out canes - this through a thick groundcover that surrounds it on one side. The other side is packed with azaleas. Wondering if I need to make a pathway in and deadhead it for more blooms or if it is just a one time bloomer. Anyone have any idea what type of rose we have growing? Thanks!
