Steve, It sounds like you have Bacopa amplexicalus (used to be called B.
caroliniana). If that is what it is, it will have a pronounced 'herbal'
odor when you rub a leaf.   I used to have this species in a five gallon
aquarium where it pushed above the surface and bloomed regularly.  It never
produced any seeds, however, and I never was interested in trying to cross
fertilize the flowers because the plant is so easy to propagate
vegetatively. I have Alternanthera (species unknown) that self-fertilizes
and prodices seeds, and I used to have water hedge, Didiplis diandra, which
also produced floating seeds that later sank and germinated.

You can try growing it emersed and then transfer pollen with a toothpick
from one flower to another.

Bacopa Caroliniana does reasonably well in low light tanks. Bacopa
monnieri (dwarf bacopa) requires somewhat higher lighting levels. I
grow both in bright light myself. The former is truly an excellent
choice for a tank. The latter tends to grow emersed where possible.
