Re: E. cordifolius


I am surprised that anyone would discourage hybridization of aquatic
plants, since some of the popular Echinodorus that we drool over are either
hybrids or mutants (e.g. E. oriental, E. rubin, E. sp "rose", E. ozelot
"red flame", E. osiris, etc).

I don't really understand this part. Do you mean to say that you actually
got seeds from crossing wild type E. cordifolius and marble queen? Or do
you mean that you grow the two plants side-by-side and the plantlet that is
produced is not as robust as the original?

How do you distinguish between "amateur hybridization" and "professional
hybridization"? Besides, how difficult can it be? And, I personally haven't
seen any "trash" byproducts of the plant hybridization attempts. Have you? 

I can't believe that not a single one in this list has attempted to
hybridize an Echinodorus. Tell me this is not true. How about Aponogeton?
