Hybrid Hopes

With the pest situations under control, and my new passiflora all flourishing, I have a new goal. I hope to breed a new hybrid and give it a registered name! It seems that the number of hybrids on the scene and up for sale lately has grown exponentially. However, I've noticed, or at least perceived a lack of subgenus tacsonia hybrids. Having said that, I do have 'Mission Dolores' in Pergola-tory, but other than that I haven't seen too many others. I was also lucky enough to score a parritae and exoniensis this Spring, and they're both doing marvelously. In fact, I think the botanical zone that I live in is near perfect for them. So, getting back to my goal, I hope that I can create a new tacsonia hybrid, but I could use some advice! Have any of the seasoned veterans of passiflora horticulture tried the tacsonias? What would you recommend as parents? I'm anxious to hear from you!
