I was wondering if anyone has had any experience with this vine as a hummingbird attractor? I recently purchased this vine in hopes that it would be used by the local Annas hummingbirds at my parents house. Upon inspection it was apparent that the flowers contained large amounts of nectar so although I hadn't heard of this vine I figured it would be to the liking of the hummers. Any information regarding wether hummers use this vine would be greatly appreciated, thanks in advance!
