I really want to understand if Echinodorus Grandiflorus and Echinodorus Grandifolius are the same plants. But, in fact, it is "wrong" (I don' t know!!).
I only see Echinodorus Grandifolius in trade. I cannot find scientific knowladge. But I found and read a lot of Echinodorus Grandiflorus articles (Christel Kasselman).
What is the diffrance? Please someone tell me. I really appriciate.
And one last question: where can I find real "Echinodorus Grandiflorus Grandiflorus". The biggest echinodorus. I read some where it grows up to 6-7 feet.
