Hi Joy, Gladiolus is a very large genus and the names have been changed around a lot over the years. You could start a list by finding and listing all the "accepted" names on The Plant List: http://theplantlist.org/tpl/search/… The "accepted" ones (not everyone agrees) are in bold. Then try looking on the Silverhill Site: http://silverhillseeds.co.za/ByName.asp/… and make a note of the ones that they say are summer growing. The rest are winter growing. We have quite a lot of information on the African Gladious on the wiki thanks a lot to Rod and Rachel Saunders and Cameron McMaster who have supplied a lot of photos. But there are wiki places pages that would allow you to make a note quickly as well. All of the glads listed on these pages will be winter growing: http://pacificbulbsociety.org/pbswiki/index.php/… http://pacificbulbsociety.org/pbswiki/index.php/… http://pacificbulbsociety.org/pbswiki/index.php/… http://pacificbulbsociety.org/pbswiki/index.php/… http://pacificbulbsociety.org/pbswiki/index.php/… All of the glads listed on these pages will be summer growing: http://pacificbulbsociety.org/pbswiki/index.php/… http://pacificbulbsociety.org/pbswiki/index.php/… The miscellaneous wiki page has the European ones that people have provided photos for so you could add those to the winter growing list: http://pacificbulbsociety.org/pbswiki/index.php/… Also if you went through the wiki Gladiolus pages you will find a lot of them described by where they are found. You could click on the species in the table on the main page you have not yet identified. You have to know something about the geography of the various locations as the listings don't always say winter or summer growing, but usually say where that species is distributed. Overberg would be winter growing as Cameron provided a lot of photos of that. If you find more locations for the Gladiolus missing after that in the search here: http://ville-ge.ch/musinfo/bd/… The African species are listed here : TA = Tropical Africa Area (EPFAT Area, country-based, south of the Sahara, complementary to the following) SA = Southern Africa Area (South Africa, Namibia, Botswana, Lesotho, Swaziland) NA = North Africa (Mauritania, Morocco, Canary Isl., Algeria, Tunisia, Libya, Egypt, Madeira) MA = Madagascar (Malagasy Republic) You can limit your search to one or more of those. It you chose SA and clicked on each species you didn't have after you had done the rest you will find a map and a location. WC (Western Cape) will all be winter growing for instance. If this sounds like a lot of work, yes it would be. Everything that has been added to the wiki represents work by some volunteer. But it would be a valuable addition to the wiki and I'm sure the current wiki administrators would be happy to add it. Mary Sue
