I don't have dwarf, but I have some big ones.
One or two avalible Amazon Sword (Echinodorus amazonicus).
About 10" tall by 8"+ inches wide.
$10.00 each, plus priority mail shipping from Connecticut.
(I roughly estimate shipping at $6 - $8)
I also have a baby about 4" tall by 3"-4" wide for only $5.00.
I can take PayPal.
I also have some smaller youngsters of another species of Amazon sword plant.
I have to try and remember exactly what the name of it is.
It has larger, rounder, and much darker color leaves.
I can try and get you pictures if your interested.
Please email me
thanks
