The leaves of some myriophyllum species (M. alterniflorum) differ
greatly in appearance depending upon the substrate in which they
are grown. The leaves of the above species were much longer in
loam and peat than in sand. (from Aquatic Botany 10: 383-388)

There apparently are quite a few species of myriophyllum in North
America, often difficult to identify and distinguish.

I'm sure it's a Myriophyllum, although it's hard to be sure which one.  M.
pinnatum is usually sold as "green foxtail", and M. heterophyllum is
usually sold as "red foxtail".  But I've  also seen other species being
offer with that name.  And, yes, it's a very hardy, pretty, and fast
growing plant given even reasonable conditions.  Be _very_ careful not to
let it escape.  Some Myriophyllum is winter hardy, and this is just the
kind of plant that can make legislators want to shut us down if it starts
clogging local waterways.
