Growing from seed versus importing bulbs from another hemisphere

For a number of years I would reread Stan Farwig's article A NON-CONCISE 
GUIDE TO THE CULTIVATION OF BULBS. He was correct, it certainly wasn't 
concise. Still I found it very interesting as he and his partner grew a 
lot of bulbs very successfully and each time I read it I was reminded of 
something very valuable I had forgotten. It's on the wiki, but not easy 
to find and doesn't work for short attention spans.

But I'll quote from a section of it that addresses Jane's comment

> A vexing problem when obtaining bulbs from the southern hemisphere is

> and one must choose between allowing growth to commence and hope they

> "off-season" period, or attempting to prolong their dormancy until the 
> proper season arrives and hope they do not become too desiccated (as 
> is more likely to happen in very young bulbs). Our experience has been
