CULT: Purple ringed rhizomes


Hi All,

I posted something about this a while back and received a private reply 
from Roger at Superstition. In unpacking my orders and gifts this year, I 
noticed a few rhizomes with rings of purple coloration encircling the 
tops of the rhizomes - not PBF, as the color didn't extend up the leaves 
at all - just purple-ringed rhizomes (PRR for abbreviation's sake - 
thanks, Janet).  Roger suggested this phenomenon most often occurs in 
SDBs, though it can occur in other classes as well.

It has been suggested to me that it might be useful to add a PRR list to 
my website iris pages along with my current PBF list as one more element 
of cultivar identification.  So ... if any of you know of any irises you 
are growing that exhibit PRR, please let me know.  I realize this is not 
something you will be able to observe in the garden.  It'll only be 
evident on dug and washed rhizomes (obviously NOT the best time of year 
to be making this request). Anyhow, keep it in mind for future reference, 
please.

Thanks!

Laurie
