My thanks to the advice offered last year on this species{sorry I can't remember who responsed to my query}. I now have seedlings to 3 cm{excess of 150 pups!}The fertility is amazing,I accounted for only one that has not germinated. Q. Has anyone{outside OZ} flowered Echinodorus OPACUS in recent memory?
