FlowersThe flowers are funnel-shaped and can vary in appearance. They have a white base and throat and may or may not have a white edge. The color of the flowers is difficult to describe, as it can be referred to as chocolate, dusty chocolate, dusty pink, rose, rose pink, and so on. Flowers open in the morning when they get the morning light and fade in the heat of the day.

DimensionsMine have reached over eight feet in one growing season in zone #5.
Maintenance"The plants are vigorous growers and need a strong support structure. The fall cleanup is a chore, as the plants produce many vines that twine around the structure and themselves. Lots of cuts are needed to remove the vine from the structure; you can't just grab the base and pull, as it won't let go."
PropagationIt is easy to grow from seeds. When the soil temperature exceeds 50 degrees, the seeds can be planted directly into the ground. Alternatively, you can start them indoors a few weeks early in a peat pot. I have found that the seeds germinate best when soaked overnight or when the seed coat is scratched or nicked in a process called scarification.
Author's NotesWhile researching this plant, I saw many pictures of the flower, showing variation in color and the amount of color in the flower. The flowers on my plants were very uniform in their coloration.
