Thanks Christiaan--Welcome information about temperatures. Despite years of training, I still think automatically in Fahrenheit, (only) -- and "quite winter hardy" for you at -5° C is still 20 F degrees away from our winter lows. So for me to think about selecting anything to grow here in the Chicago means that I'd need a list of desirable plants at Sutherland and then I'd check to see which of those withstood our winters here. I'm sure that most folks in the PBS can get away with growing almost anything from South Africa. (No, I know it's not really true.) Might such a list be handy to you , say-- in the form of plants available from a local nursery there? ----- Original Message ----- From: "Christiaan van Schalkwyk" <cvschalkwyk@lantic.net> To: "Pacific Bulb Society" <pbs@lists.ibiblio.org> Sent: Wednesday, April 29, 2009 8:17 AM Subject: Re: [pbs] Acceptable Oxalis > Hi all > > Most of the winter growing south african species of Oxalis should be quite > winter hardy.
