It is not a cultivar, but I know the ONLY place where it can be found... far away from here, in South Africa... very rare&beautiful..
....and one more place, not so far - STC, Robert Wellens :)
still very little, but I'm absolutely happy - a year ago I couldn't dream to get this plant, it's really very rare...
by the way Hayashi give this name "Haworthia mirabilis "pilosa"" to this species just in 2004, 8 years ago...
Again a plant I search, thanks for the tip Harmony
