Re: OT: Chimera

Michelle, I am interested in hearing comments regarding your query.  Lloyd
Zurbrigg has a flower registered as I. 'chimera'.  It sounds like you are
referring to something other than this cultivar though.  If so, can you post
a link referencing what you mean by chimera.

In daylilies a chimera is a diploid plant that has been treated with
colchicine to convert it to tetraploid, but the conversion is not stable and
only part of the plant is converted.  Thus a chimera would be a plant with
diploid and tetraploid blooms on the same flower scape.  The chimera will
revert back to full diploid status.  Generally, one of the most reliable
ways to determine if a plant is a chimera is measure the pollen size with a
microscope.  This way you can determine which blooms are tetraploid and
which are diploid.  Often times, the base of the bloom will be thicker in
tetraploid flowers, too.
