The Creeping fig is probably one of the most well-known ornamental fig plants, and is seen in many tropical countries as an ornamental climber, not just for the home but also in urban settings, where it is used to decorate (sometimes not intentionally) overhead road crossings or other urban structures.
As a kid I found Ficus pumila to be a very interesting plant, because it has leaves of two forms. The smaller leaves are adpressed to the substrate (and I tend to think that they climb walls better than trees), and then when it is ready to fruit, it bears them on branches which come off and hang free from the wall, and on these branches are the large fruits.
I have never tried the fruits of F. pumila but there are varieties of this species, Ficus pumila var. awkeotsang or the Awkeotsang Creeping Fig, which is known specially for the edible figs. The figs of this subspecies are used to make a ice jelly desert in Asian countries.
