Positive QueenB On Aug 18, 2006, QueenB from Shepherd, TX (Zone 8b) wrote:

This particular species comes naturally in a wide variety of patterns, colors, and both flower and leaf types. It's very partial to hot, humid areas with a moderate amount of rainfall. It's not uncommon for this vine to grow several feet in length and make copious amounts of seeds.

The "Japanese" types tend to be more delicate, having a sensitivity to high temperatures and full sun. Most are variegated, and the leaves will sometimes burn. Typically the vines will fail to thrive and set pods. These kinds do best in partially shaded areas. Some dwarf varieties do well in hanging baskets or containers since they don't climb, but sprawl.

Neutral Crimson On Sep 2, 2002, Crimson from Clarksville, TN (Zone 6b) wrote:

Not a climber... a sprawler, good for hanging baskets. Foliage has to be trimed or many of the flowers will never be seen. Common MG size flowers with white rim.
