Gloriosa superba grows from a tuberous rootstock into one of the most theatrical vines available to gardeners in warm climates. The leaves are strap-like with tendril-tipped ends that catch on any nearby support, allowing the plant to scramble up a trellis or through neighboring shrubs to 6 to 8 feet. The flowers that emerge on long stalks are six-parted, yellow shading to red at the margins with wavy, reflexed petals that give them the appearance of something in motion even when still. It is a plant that stops visitors who think they know what a lily looks like.

In zones 8 through 12 the tubers can stay in the ground; elsewhere they should be lifted after foliage dies back and stored dry over winter. A trellis or other support is essential, and the stems should be handled minimally when training to avoid damage. One important caution: every part of this plant is highly toxic, the tubers especially, which resemble yams closely enough to pose a real risk. It should not be planted where children or foraging animals have access, and care should be taken when handling the plant.
