Hi: I will be growing my primroses in zone 5--it can be quite wet in the winter with some mid-winter thaws. What primrose species would do best in these conditions? What type of soil is best for use in a cold frame for primroses? -- Diana Pederson, Zone 5, Michigan http://www.geocities.com/RainForest/9251/index.html http://www.suite101.com/topics/page.cfm/262
