JB,
I've only seen 'Green Bonnie' at Wal-Mart. The cultivar name is an Exotic Angel tag, so I don't know if there's another name for it. It seems rather uncommon here, I've only seen two or three at most. Just imagine 'Bonnie' without the white in the leaves. Pure green leaves, but it's still curly like 'Bonnie.'
I think your 'Fireflash' looks fine for its size. Here's a link to a blog that shows a picture of an older specimen.
http://plantsarethestrangestpe... I used to see 'Fireflash' a lot when I first got into plants years ago, but I haven't seen one in a really long time.
I haven't heard of 'Shamrock' before. I think one of my 'Spider Plants' is just your plain 'ol all-green variety.
I have only four 'Spider Plants' myself. They are rather tough plants for sure and it's nice that there are so many different cultivars. Even my Mother hasn't killed hers yet, which says something.
The last one you showed and described reminds me of 'Hawaiian'. Do you think it's possibly a 'Hawaiian'?
