Ms. Walstad has a whole section in her book on the "aerial
advantage," which covers the good things that happen when
plants can grow above the water line.  If you don't have
the book yet, consider purchasing it from the AGA websit or
take a look at Diana's own website:


Many of the plants that we grow under water naturally occur
along the banks of lakes, streams and rivers, and while
they can grow under water and therefore endure rises in
water levels, they do best when growing emersed.  I think
that some of the plants we grow, we are giving them a hard
time by drowning them.

Also note that, if you are lighting your tank from above
(who doesn't?), then the emersed growth is closest to the
light, getting the most light, completely unfiltered by
