Aponogeton Culture

I found a packet of "Hybrid Aponogeton Bulbs" at Wal-Mart 
yesterday. (Seven "bulbs" for $2.79)  I could'nt resist 
their purchase after reading the blurb on the back of the 

. . . Aponogeton bulbs are one of the easiest aquarium 
plants to grow.  They thrive in almost all water conditions.
   Just drop the bulbs into the aquarium and watch them grow 
(6" to 8" in just fifteen days).  As the roots develop, the 
plants anchor themselves or can be planted in the gravel for 
faster growth.
   The lush green leaves provide a rich, natural background 
in any aquarium.
   Provide them with at least 8 hours of light a day for 
fastest growth.
   In 3 or 4 weeks your plants will have white and pink 
blooms.  These can be cut off to promote steady plant 
growth. . .

Can anyone give me any more information?  What are the 
plants temperature,ph, nutritional and light requirements?  
My literature indicates a variety of species with varying 
requirements and refers to seeds not "bulbs".  The package 
is marketed by:
