Seeds from Gloriosa Lily Carsonii. A cold tender vine that attaches to a trellis via tendrils that grow from the tips of its long, pointed leaves. During warm, rainy months, the vine produces 3 inch, inverted flowers that are solid yellow when they first open, then develop purple and chocolate splotches, and eventually age to a uniform purple color. The foliage is glossy, bright green and oval with tips that often form tendrils. Zones 8 to 11.
