There is a lot of information available on this. For instance, the list of oficial Mexican spp. arenicola bella carinata/grandiflora chichimeca citrina clintiae crociflora fosteri katherinae latissimifolia lindleyana longifolia macrosiphon morrisclintii (they merge Cooperia into Zephyranthes) nelsonii nervosa nymphaea primulina pulchella reginae subflava verecunda are all from alkaline to very alkaline soils and dry winter dormancy. "Labufarosae" also belongs here but has not been published as a species to my knowledge. And it is a very good one. Also huastecana. > Date: Sat, 23 Nov 2013 13:31:50 -0500 > To: pbs@lists.ibiblio.org > From: jshields@indy.net > Subject: Re: [pbs] Getting Rain Lilies to Bloom > > Also note that Charles grows his rain lilies in the university greenhouse > -- heated in winter and cooled in summer.
