Cryptostegia grandiflora

Rubber Vine

A woody vine that can grow as a small shrub or, if support from larger trees is available, as a rampant climber that can grow an amazing 5 m (16 ft.) in a single month. Originally native to Madagascar, it has now naturalized in many other tropical countries and is considered a noxious weed in Australia. In other places in the tropics it is still popular as an ornamental for its pretty flowers and its commercial grade latex. It should, however, be situated with care due to its invasive potential and its toxicity to livestock.

... are very difficult to germinate.
I have tried several times even with 100 seeds but never had succes. Maybe some special substrate needed and/or the necessary unknown deep location.

The Encyclopedia of Cultivated Palms is the definitive account of all palms that can be grown for ornamental and economic use. Palms are often underutilized as a result of their unfamiliarity—even to tropical gardeners. To help introduce these valuable plants to a new audience, the authors have exhaustively documented every genus in the palm family.
825 species are described in detail, including cold hardiness, water needs, height, and any special requirements. Generously illustrated with more than 900 photos, including photos of several palm species that have never before appeared in a general encyclopedia, The Encyclopedia of Cultivated Palms is as valuable as an identification guide as it is a practical handbook. Interesting snippets of history, ethnobotany, and biology inform the text and make this a lively catalog of these remarkable plants.
