Lovely plants! Lucky you!!
Once you get the hang of how names work it's not too difficult to figure out. Taxonomists have been very busy reclassifying many plants in the Catt alliance, so many things have changed. Keep that in mind as we go along.
Your first plant's name is Gsl.(previously Lc) JoAnn Amos. It is a hybrid of C. walkeriana and Srt.(also formerly Lc.) Rojo. When the name begins in upper case you know it is a hybrid. When it begins in lower case like walkeriana you know it is a species. Gsl. JoAnn Amos is a cross of a hybrid and a species. It's quite lovely!!
Your second plant is Sc. (formerly Lc.) Egeria coerulea (coerulea denoting it's blueish color). It is a cross of Sc. Canhamiana and C. walkeriana. Again a cross of a hybrid and a species.
The third plant is Rsc. (formerly Blc.) Kat Red Panda. It is a cross of C. Moscombe and Rsc. Golden Slippers. This is a cross between two hybrids. The 'Totale' would indicate a cultivar name only given if the plant had been awarded. I can't find any awards for Kat Red Panda or any of it's parents. So not sure what to tell you about the 'Totale'. Perhaps wishful thinking on the growers part?
Clear as mud right?
