During our recent holiday we visited the rainforest in Costa Rica at the La Selvas Biological Station where I picked up these seeds. They are about 2 inches in size. I was told they were from the "bean tree". Ever keen on challenges I brought them home wrapped in wet tissue and am intending to see if I can grow them as a pot plant. The tree they came from was very very very tall. So if I am successful with growing them I will possibly have to donate them to the Ventnor Botanic Garden for their tropical greenhouse!!!!!
One of the seeds was sprouting when I wrapped them, but the green tip has turned brown in travel. The other was completely dry when I packed it but has now split and the shoot is growing. I'll keep posting my progress!
