Wow! Those are spectacular. I'm jealous. I have no idea about classification but....those are really gorgeous and you are fortunate. I especially like the third photo, the green one.

Yes you hit gold! That is what I always look for. A while back I found the same with my searches. What they turned out to be was 'Flame'. They ended up growing to futura size and got more beautiful with age. Yours may well be something different but just as nice.

Another strange event I have noticed. One side is more variegated than the other? Pups forming from that side is more evenly variegated while the pups on the other side of the same plant turns out to be normal to marginated. So it would be nice to see what pups they produce.

BTW, where did you find them? I have found mine at Lowes or some times Home Depot. But that was many years ago and haven't been so lucky in the last 5 years.

Thanks for the replies guys and as Stush says yes the variegation does seem to be more prominent on one side of the plants. These plants are in Australia and were just found at a Sunday market stall.

Get to know the seller and see what else they may have and any ideas of what happened.

Looking again on this post; I believe you got a futura sized plant and not a hahnii. Looks to be Gold Flame. That was the way I purchased mine. Thinking it was Black Gold with extra stripes. Mine stayed small for a few years before it took off to now over 15 inches tall.
