Ornamental sweet potatoes such as 'Marguerite' or 'Blacky' bloom here in
College Station, either in the greenhouse or when planted out.  The
flowers are not flashy, having sometimes fleshy-whitish-or-greyish tones
with a darker center.  They're small, too, and don't last but a day. 
Haven't seen any seed balls, but in the greenhouse there may not be any
proper pollinators.  'Marguerite' when pulled up in the fall has many
large, white tubers left behind.  Even though in most winters there is
nothing but a few frosty nights (above 25F) no ornamentals seem to last
through the winter outside.  Real sweet potatoes are perennials in my
garden.  If you get by without an infestation of mites or aphids, cut
pieces of ornamentals can be overwintered on a windowsill in a colored
glass bottle with water.
