Since it is evident that a lot of members are not only banana crazy, but generally enjoy any interesting plant, I thought I'd submit the Tomatillo for consideration. Originating in Central America, they are closely related to tomatoes, in the family Solanum. Sometimes called Husk Tomatoes, they are physalis philadelphius, perennial within it's native climate, and very easy to grow, having cultural requirements similar to tomatoes. They should not be confused with a similar sounding plant of the same family, the Tamarillo, which is a shrubby tree also of Central and South American origin, widely grown as a Tomato Tree.
Both are very productive as fruiting plants in the landscape, and the tomatillo, in particular is very versatile in the ways it can be used. Each species has excellent entries on Wikipedia. Pictures of tomatillo can be viewed at banarama2's photo gallery, while the tamarillo can be found at the Hollyberry Lady's photo gallery.
