I grew Wild Irish for several years. It increased well and I found it to be fertile both as pod and pollen parent. Of course, I live in the same state as the hybridizer although I am probably about 200 miles north and a little east of the hybridizer's location.
I was particularly impressed with Wild Irish as a pod parent as it gave strong colors anywhere from purple through burgundy to red and even bright pink when cossed with anything in that same color range. As a pollen parent and crossed with a northern pink ('hard' dormant), it gave from pink through an amber/red color that was somewhat unique - at least to me. The cross with the 'hard' dormant resulted in 100% dormant seedlings although crosses with either Sev's or Ev's yielded those same two types. Out of about 25 seedlings, all but 2 had edges, many heavy edges but thinner edges too (none that I would have called "wire" edges), but teeth too. Here are some pictures of my Wild Irish seedlings:
