Answer: Hi Mike!
It sounds as though you're having fun with your plant propagation. There are several things we look for in a new plant. First, it has to have superior horticultural traits. And, it needs to be something gardeners really want to purchase. Otherwise, the 5-6 years of evaluation and propagation it normally takes before a new plant is introduced to the public won't be very economical.
Superior horticultural traits include but is not limited to:
Unique or superior foliage form or flowering
Ease of propagation and cultivation
Distinctive growth habits
How do your new plants differ from similar plants on the market? Why would others want to grow them in their gardens?
It's really important that you keep lots of records so you can prove you actually did produce a brand new cultivar and what you have is not a natural sport or a reversion. And, you'll want to get a Patent on your plant to protect it from unauthorized propagation.
Since you're just beginning to see the fruits of your hybridization labor, you might want to contact the Horticulture Dept. of your local branch of California State University. Professors there can explain the process and lead you through the myriad of paperwork required to authenticate and register your new plants.
Best wishes with your new plants.
