What are the pros? Prolific
What are the cons? None
I planted these onions last Spring (2012). I purposely didn't touch one of my rows and let the onions go through the winter. They made it through the harsh winter just fine (our average high was 19 degrees in Jan). In fact, they propagated (bunched up) very well. I separated them and replanted this Spring (2013). At the rate they propagated, I figure I'll have Red Welsh onions in my garden for life. They seem to be very hardy. About twice (or even 3X) the size of a typical green onion you find in the grocery store. They taste great. I highly recommend.
