This is one of my favorites too, can't wait to see mine bloom. There are actually four registered Fanaticum hybrids, Carolyn Butcher (x delenatii), Krulls Lace (x roths), Dick Wagner (x bellatulum), and Tzeng's Ace (x S. Gratrix).
Heh, well it does look like emersonii but it's Orion's Belt (emersonii x Muriel Constance). The emersonii is very dominant in this cross. I do have a couple emersonii budding up, so you'll see those in a month or so. I have good news, we have many seedlings that came out of flask a few months ago of our largest emersonii (about 5 inches across I believe)!
