silvarerum Interesting to note, too, that while a lot of winter tulip growers tout "buy local," some studies suggest that imported roses might have a smaller carbon footprint. Flowers are flown in full airplanes in cargo, the flowers don't require heated spaces to grow, employees often live close by and walke bike to work, etc.
Thought I'd add since you were all talking here about the SA flower industry. (In Europe most of the roses and industry flowers are imported from Kenya where similar logistics apply.)
ETA: Last note I am now using my tulup growing space (which was apparently too humid for some of my tulips varieties and many had stem topple and other growing problems last year) to start my dahlias and mums and I am much happier with this! No more tulips for me. 🙂
