Cal-Sibe Iris
James Waddick (Sun, 16 Mar 2008 09:45:21 PDT)

Dear Dan and all,
The Cal-Sibes or Calsibe are a valid and growing group of
hybrids. They are formed by the cross between a Pacific Coast Native
iris (PCN) (all of which have 40 chromosomes) and a Siberian Iris
with 40 chromosomes, the Sinosiberian sub-group.
There are dozens of these named cultivars. One of the most
influential hybridizers is Dr. Tomas Tamberg ( see
http://translate.google.com/translate/…)

and others in the US such as Jean Witt and Lorena Reid come to mind.
You can see quite a few at
http://tamberg.homepage.t-online.de/homep9e.htm/ and scroll down
to click to other pages including back crosses called 'Sibcal
hybrids'.

They do best in areas where the PCNs and Sino-siberian do
well, but some of the hybrids are more widely adaptable than either
parent.

Try some. Jim W.
