  variegated aroids

I have been trying to increase my collection of some of the rarer variegated aroids and have been told that variegation is not stable. Why wouldn't it be stable if It has been grown like that for a time or found in the wild that way? How would I keep it variegated?

Albert,

There is a good article on the Web on the origin,
development, and propagation of chimeral variegation by
Daniel Lineberger of Texas A&M University at
http://aggie-horticulture.tamu.edu/tisscult/chimeras/chimeralec/chimeras.html.

Michael Marcotrigiano is an expert on chimeras and
variegation. You can find references to his articles at
http://www.science.smith.edu/~mmarcotr/Researchprofile/resume.htm.

Regards, Scott

Depends on whether the variegation is caused by pattern genes as in
Dieffenbachia or chimerism (genetic mosaics). Chimeras can be stable if
they are periclinal chimeras (rare in aroids). If the are splashy types
with wild segregation you select branches or divisions with a nice
variegated pattern. All green ones get thrown out, all white ones die if
disconnected from the parent plant. I wrote a extensive review on this
subject if you want more info. Its in HORTSCIENCE vol. 32 Aug 1997. page
773-784.
