H. difformis, when it has good light, adequate CO2, and some room to spread
out, will send out stems that run along the bottom surface.  Later, from
the nodes of these prostrate stems upright stems will grow.  In this
manner, it can colonize and take over any well lit area that isn't already
inhabited by other plants.  The prostrate stems will switch to upright
growth, however, if they grow into shaded areas.  It may be that in your
aquarium there is just enough light for the plants show just a bit of the
horizontal growth.  Probably with less light they will grow straight up,
and with more, they will have more horizontal growth.

Try Darin Gasperson:
Also, try Delaware Aquatic Imports (Mike Tzronkowski?).  I don't have
Mike's address right here, but he advertizes in Freshwater and Marine
Aquarium (FAMA).
Horizon Growers can appearently get plants from Tropica, and you can see
what Tropica carries at
Horizon has ads in FAMA and/or TFH.
