Emersed vs. Immersed Echinodorus
Here's another interesting "emersed vs. immmersed" story.
I got something from Darin Gasperson at Aquatic Greenhouse in Florida,
which he "thought might be" Echinodorus harbichi (or perhaps it was
harbichii--his handwriting wasn't quite clear). I haven't seen
anything quite like it before. Light, almost pastel green, broad
leaves about 12 x 8 cm on 8 cm petioles. The Dennerle book shows
something called E. cordifolius HARBICH, but this didn't look exactly
like that, or like any cordifolius I've seen...the leaves weren't
cordate. But it was a pretty and robust plant, so in it went. It
immediately reverted to a deep red E.osiris. Unfortunately I already
have one exactly like it in there already...
