Why not try growing a coconut? When choosing a coconut for germinating, choose a fallen nut in which you can hear water slosh when you shake it. Leave the husk on. Soak it in a pail of water with no chemicals in for two or three days before planting. To grow a coconut palm as a house plant, use in a shallow hole, burying only the lower third of the nut. Give it a good feed of organic liquid seaweed!
