Got a small plant.
It grew very fast, but still below 2 ft when winter arrived.
It overwintered without problems in our cool winter (50F/10C).
We only had one or two nights that the temperature dropped close to freezing point and it had no problem.
In March it started to make flowerbuds and it's going to flower soon despite the small size of the whole plant!

I found this plant at Western Hills Nursery in Occidental. The leaves are attractive and shiny. The brown/maroon flowers are fascinating, with an unpleasant, but not horrible, scent. I have had great success with a native California pipevine, so I am looking forward to growing this one. It has not gone through a winter yet. I am a bit concerned, as we can often go below 25 degrees F. I have it planted next to my driveway so I can enjoy the weird flowers close-up.

This is a vine from the brazilian coastal vegetation, specially in the Rio de Janeiro state, being fairly common on the board of the forests and Restingas.

Its a climbing plant that can be massive after some years, even covering short trees and shrubs completely. It has lobate, fuzzy, and rather thick leaves.

The flowers are at least one of the weirdest Ive ever seen. The petals are vestigial and unimportant. The fused sepals are the main atraction here, forming a sinuous tube (where insects get traped, being set free after the stamens get mature and cover them with pollen) that opens on a triangular, petal-like structure. This "petal" is marron, and has a long tail on the top. I mean, a looooooong tail, reaching up to 1 meter long! The flower is 1 meter lon... read more
