Here's a tropical vine to try. Spotted at Kuhlmann's Market Gardens and Greenhouses a couple years ago, I could not resist taking a photo. It is the most splendid tropical vine I have yet seen. Originating from tropical Africa and Asia, the glory lily is the national flower of Zimbabwe. The glory lily's botanical name is Gloriosa superba. Hardy in zones 10-11, sometimes zone 9. Otherwise it makes a stunning annual vine.
Climbing from eight to 12 feet, the glory lily is a vigorous vine perfectly suited for a trellis. The flowers have yellow margins on red petals and look somewhat spidery with long stamens protruding.
Plant in full to part-sun in well-drained organic-rich soil. Use a balanced slow-release fertilizer. The tubers can be dug in the fall, stored much like a gladiola bulb and planted again in the spring.
