Lisa, Apparently I was confused! I did some research, and while softnecks can produce scapes, it isn't all that common - sometimes from stress and sometimes no clear reason. But in general, forming flower stalks has largely been bred out of the softnecks.
I started out with 6 varieties, including 3 softnecks, about 10 years ago, but was unable to keep them completely separate. Based on appearance and storage ability I thought I still had 2 "soft" necks, but maybe not. Although the softneck scape anecdotal comments I read often mentioned Inchelium Red, which is one of the varieties I started out with.
Here are a couple of links - I especially liked the Hood River Garlic Growing Calendar:http://vegetables.wsu.edu/GarlicScapes.htmlhttp://www.hoodrivergarlic.com/garlic-calendar.htm
