Re: [aroid-l] variegated

Michael,

Let me venture an explanation. Some variegation are chimeral, which means only some part of the tissue is genetically different. In variegation, the difference is in the color, so you have patches of normal green and patches of abnormal color, often yellow or white, side by side. The genetic variation in chimeras usually cannot be transmitted to an offspring sexually, however, offsets or pups can often get the same or similar genetic variations in tissues.

Yes, you're right about that.  Those hosta used for breeding are not so easy
to find, just like this konjac:-)
But it still is a bit weird to me that something genetic does not happen all
over the plant.
Any explanation for that?  If not, I guess I'll just have to accept the
facts:-)

Best,
Michael
