Stems
Stems become woody and are usually climbing, reaching 20 to 40 feet in height. Stems climb by way of tendrils.

Flowers
Flowers occur in clusters of 2 to 5. Individual flowers are approximately 2 inches in length and are dull red to orange on the outside and yellow or red on the inside.

Fruit
A flattened capsule that is approximately 6 inches long and 1 inch wide. Each capsule contains several rows of winged seed.
