A slender perennial vine, woody at the base, with 4 inch long heart-shaped leaves. The flowers are white, in large clusters, 1.5 inches wide. The fruit is a one-seeded capsule. Native to tropical America.
Cultivation and Propagation: Cultivate much like the morning glory except that it is less hardy and should be started indoors in the North. It will also take more water than the common morning glory and, as it is somewhat woody, it can be cut back and brought indoors to carry it over the winter in the North.
Harvesting: The seeds should be gathered as the pods turn brown and dry.

...with R. corymbosa don't let the seeds get too wet or they will rot, much like Argyreia nervosa.

Alsius (Shroomery forum): Give em a very moist rich tropical composty soil, germinate therein. Give seedlings plenty of light and wait about a month. When you notice slow growth and a few new leaves transplant into a rich soil. Water regularly and provide a trellis to climb on. They will go haywire and spread very rapidly. My plants have turned woody and I rarely water now. I also give them a strong bloom fertilizer. I have yet to see any of these flower. Ever. No matter what I do, I cannot get it to produce. Grrrr.
All of them have turned woody(which I hear is a step from flower).

It has masses of tubular flowers when grown and grows excellently in sub-tropic environments. Will bloom twice year and dose not die back, can grow very large in time.

Ringworm (SPF Forums): Rivea is also easy to root, although seedgrown plants are sturdier in the first year or so of life.

Jacko (SPF Forums): Well, all I know is that they're not hard to sprout and that you can grow them for years without them flowering at all. Stonehenge (SPF Forums): My older one grows a while and then dies back, grows a while and dies back etc.
Dendro (SPF Forums): rivea's are tropicals, mine set plenty of seed in Hawaii.

Murple (SPF Forums): Ive had T. corymbosa seeds take up to 9 months to germinate... though usually they germintate in about 2 weeks. Treat like any other morning glory.
