Hello everyone! I need some help identifying this plant. It is in a planter with a hibiscus and another plant. I purchased the planter this summer. I know the hibiscus is not winter hardy in my zone 5 and I am assuming this plant probably isn't either, but I have looked and looked and cannot find what this plant is. I have already brought this planter in with the intentions of separating it next spring. It blooms salmon/orange clusters, has a woody stem and smooth, dark green leaves that remind me of a mandevilla. Please take a look at the attached picture. Thanks in advance for all of your help!
