...sigh: Our mailing lists munges another bullet list in an email. Do we really still need to exclude even basic html markup from our list? Text-only email readers are a bit old-school to constrain the mailing list as of 2015, right? But back to my reply: In principle, any Calochorti with the same chromosome count can hybridize (C. luteus and C. superbus are just one example of this). If you want to avoid hybridization in your garden, you must prevent pollinators from spreading pollen between compatible flowers. This can take the form of: - only growing the plants in a pollinator-proof enclosure - removing the pollen producing organs from each flower as they open (but you won't get mature pollen this way) - covering each flower with a mesh hood that excludes pollinators (some of which can be tiny) - only collect/grow species with: - different chromosome counts - different bloom times -|<ipp > From: kimcmich@hotmail.com > To: pbs@lists.ibiblio.org > Date: Fri, 8 May 2015 16:26:20 -0700 > Subject: Re: [pbs] Calochortus hybrids > > Jim, > > In principle, any Calochorti with the same chromosome count can hybridize (C. luteus and C. superbus are just one example of this).

Do any other combinations hybridize? How does one prevent hybridization in a garden setting where you may have several species in close proximity, and you want to harvest the seed? > > Jim > > _______________________________________________ > > pbs mailing list > > pbs@lists.ibiblio.org > > http://pacificbulbsociety.org/list.php > > http://pacificbulbsociety.org/pbswiki/ > > _______________________________________________ > pbs mailing list > pbs@lists.ibiblio.org > http://pacificbulbsociety.org/list.php > http://pacificbulbsociety.org/pbswiki/
