I purchased two roses that appeared to be identical about five years ago. One was named, the other not. They were the same and were Marie Luis Marjan. These bushes have glossy leaves and constantly send our clusters with the occasional single bloom. It is vigorous and it sends out arching canes. The blooms are very pleasing. I think you could train it on to a moderate sized trellis. I would recommend it for mild temperate climates like we experience in Toowoomba, Queensland, Australia.
