Bromeliad, Aechmea
Use bromeliads for a tropical effect in shady regions of the landscape.  It is okay to plant some varieties in full sun as well.  You can remove pups from adults and give them to your neighbors.  Keep water in the cups but don't let the water stagnate or mosquitoes may pose a problem.
