As the author of that Dirty Dozen article, I commend you! Even where you are not sure, you are right in being not sure.

The one you list as Hyacinthina might instead by Candy Hearts. If you have a Gold Standard (or even Striptease), Hyacinthina's blooms would be nearly identical, where those on Candy Hearts might be different or at a different time.

Beware your second Undulata Univittata. The "one stripe" has become so narrow that it might disappear to become Undulata Erromena. You might preserve its current look by digging it and dividing it into several pieces.

As to your "Green Gold" (actually named 'Fortunei Aureomarginata'): I wouldn't name it for sure until it's rescued and let to grow on its own and show its mature character.

is that slug damage???

DTeager, thank you! I appreciate the confirmations and suggestions. Candy hearts is definitely a possibility. And I’ll “rescue” and keep an eye on the Aureomarginata. :) I also plan on dividing the Undulata if I remember and have time, but I’m not too worried about it as I have quite a few of those. Thank you also for writing the article! It is so very informative and helpful.

Ken, I’m pretty sure.
