I've searched the internet all over trying to find even one paper mail order begonia catalog. Does anyone have any suggestions?
Logee's. I usually get 2 to 4 each year.
If you order from Glasshouse Works or Kartuz you will usually get their catalog. GHW will not have pictures (or they didn't used to have any in their catalog - just some crude sketches here and there).
Catalogs are basically what you will see on line and I wished I could tell the companies to stop sending them to help save trees and landfills.
