Hello I'm not sure if different roses are actually different species or not. Are all decorative garden roses still the same basic rose? or do they become different species with all of the culturing that has happened over the decades? These are a couple of roses from the Rose Garden in Stanley Park. Would anyone know what they might be called?? Thank you Michael
Basically species are the plants as they occur in the wild. Try getting a good rose book because, and I mean this in the nicest possible way, you need a bit more knowledge about how species, cultivars and hybrids work or it's all going to get very confusing very quickly. I have some articles on my website about the history of roses ( http://www.botanicalstockphotos.com/articles/article-index.html ). You could start there and I also have plenty of rose images ( http://www.botanicalstockphotos.com/photos-roses.html ) that will give you an idea of just how diverse today's garden roses are.
Others often can't tell for sure what plants are from close-ups that only show a small part of the plant. With a huge group like hybrid roses you really need to show multiple pertinent details including appearance of flowers at different stages, leaf, stem and bud features and so on.
That would make it simple. Maybe if you can get there on a day when there is staff out working in the garden one of them can tell you. Too bad they don't have signs on them.
