I live in southwest georgia, and I need a vine to attract hummingbirds. It needs to go up a maybe 6-inch wide tree trunk used as a pole that is less than 8 feet tall. There are hummingbird feeders hanging off the pole, and I don't want the vine to overtake those. It is also very close to the house, so I don't want anything aggressive. The only option that I've found so far is the Lonicera periclymenum harlequin honeysuckle, but I'm afraid the spread may be too much. Any ideas?
