Paul,
I just happen to own one myself. My tag saids, 'Zebra Plant Haworthia fasciata'. So you are correct.
Stush

Hey, Paul, this is one I got from John K. @ The Root System near Jackson, MI. He has it labeled as H. fasciata 'Superwhite'.

Thanks, gents. I couldn't remember if there were any other Haws that had this "look".

If it is H. fasciata, it will lack tubercles on the upper leaf surface of the leaves (smooth). Otherwise, a form/variety of H. attenuata.

So Rosemarie, based on what you said, then the plant Howard posted should be a Haw. attenuate as it definitely has noticeable tubercules on the upper leaf surface?

How smooth would the upper surface be in H. fasciata? Here's a couple more shots of my plant:

You can definitely see some fine bumps/ridges. Would this qualify as "smooth"?

Wow, Paul...that does put the tubercle or lack of...to the test! Eek! I don't know if that would qualify as "smooth".

Howard's is definitely an attenuata variety.

I'll say~ IF your plant grows in an upward fashion (get taller) over time (maybe if you repot to something bigger than bonsai pot), then yes, fasciata. It sort of looks like it is getting taller.

Here's one of mine for an example: (click for larger view)

Rosemarie, mine definitely has bumps on the upper side of the leaves and stripes on the underside, so this makes mine H. attenuata var as opposed to what the tag says, H. fasciata 'Super White'

Yes, Howard. :)

Yes, Howard. :)

Mine looks the same as Howard's. I wish it was more like yours, Rosemarie. I like the colors coming out in the pups. Orange, white/green, and ever an all white one. Nice.

Stush, that colors are that Californian sun tan that haworthias and other sucs get when grow with a bit of winter sun.

Sorry, I should've told you that it is a variegated plant. No California tan working on it this time. ;)
