I am looking to plant a vine or two. I have different areas that have full sun and areas that will get only part sun in the morning. I have planted clematis in the past and they have done well for a few years then they kinda of fizzle out so I am not reallly looking for them again. I would like something that birds are attracted to for food or shelter. I do not.... want a vine that will take over the yard. I live in zone 7 in oklahoma. Does anybody have some ideals ? Thank you Darwin
