I collected the beans on Cape Canaveral Seashore in 2005. I finally succeeded in germinating it in March 2009. Here is the story of how I germinated it. http://davesgarden.com/community/forums/t/968263/
I am now using this method to germinate the more difficult seeds.

This is a creeping plant (a climber, if it has where to climb) from the southeastern brazilian litoral, being one of the first colonizers of the beach sands, near to the sea. In fact, it´s a strong contester for other typical plants from that area, like Ipomoea imperati and Ipomoea pes-caprae .
It has leaves with 3 broad, dark green leaflets. The flower spikes bear few flowers, which are bright pink with white stripes. It has a broader petal, and 4 curved others around the reproductive organs. It has enough nectar to atract even birds, but the flower size is more suitable for bees and bitterflies. The seed pods are hard, and light green.
This plant needs white and salty sand to grow, full sun, high temperatures and air humidity, preferably humidity from the ocean. It likes moderate watering. It demands a large area to grow, but you can make it climb on something to reduce the room demand.
Also, this isn´t commonly cultivated, mostly found only in wild areas, making it an endangered species. Be careful before getting your hands on it.

Beach Bean grows all over the beaches of Cape Canaveral and Cocoa Beach, Florida. I like to collect the seeds after the pods dry, and spread them around other areas of the beach. Beach Beans help stabilize and build dunes, which give protection to people and the beach itself. The flower is a beautiful purple, and is small. The plant grows in a long vine across the beach, sometimes extending around 20 feet or more! The leaves are somewhat round-oval in shape, and fold down the centerline. Look for them the next time you're at the beach. The pods will look just like regular bean pods you see in the garden, except about 4-5 inches long and thick.
This plant has been said to grow in the following regions:
Boca Raton, Florida Cape Canaveral, Florida Saint Pete Beach, Florida Suncoast Estates, Florida
