Jim, 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 enclosureremoving 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: jimb@customwindowsupply.com > To: pbs@lists.ibiblio.org > Date: Fri, 8 May 2015 22:30:43 +0000 > Subject: [pbs] Calochortus hybrids > > Calochortus luteus and C. superbus are said to hybridize. 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/
